<br />
<blockquote>Researchers have created a new type of antenna made of liquid metal that can bend, stretch and twist, then return to its original shape, an advance in technology that could lead to new uses where resiliency is especially important--in the military, for example, or for rugged outdoor activities. </blockquote><blockquote>snip... </blockquote><blockquote>The scientists made the antennas by injecting an alloy made of the metals gallium and indium, which remains in liquid form at room temperature, into very small hollow channels the width of a human hair. They used elastic silicone channels to hold their alloy, and then fashioned wire-like antennas out of the material. The channels, which resemble straws that are open at both ends, can be manipulated into a variety of shapes.</blockquote><blockquote>Once the alloy has filled the channel, the surface of the alloy oxidizes, creating a “skin” that holds the alloy in place, while allowing it to retain its liquid properties. "Because the alloy remains a liquid, it takes on the mechanical properties of the material encasing it,” Dickey said. </blockquote><blockquote>snip... </blockquote><blockquote>Another discovery: "If you cut this device just through the metal--not all the way through--it comes back together," Dickey said. "You can partially damage it, and it will self-heal."</blockquote><blockquote>Since the frequency of an antenna is determined by its shape, "you can tune these antennas by stretching them," Dickey said. </blockquote><blockquote><a href="http://www.usnews.com/science/articles/2010/03/19/antennas-that-bend-stretch-and-twist.html">continued</a>...</blockquote><br />

Here are my favorite antenna rotators from yesteryear.<br />
<br />
<a href="http://www.rotorservice.com/prod1%20rotor%20sales.htm"><b>Norm's Rotor Service</b></a> has many rotors for sale refurbed and new. They bought the remaining stock of Alliance rotor parts and units. <br />
<br />
<a href="http://www.hy-gain.com/Catergories.php?sec=8"><b>Hy-Gain</b></a> continues to make many of the CDE model rotors. They bought up CDE when they went defunct in the 1990s.<br />
<br />
All of these rotors listed with the exception of the Yaseu, which is made in Japan, are Made in USA.<br />
<br />
<b><span style="font-size: large;"><span style="color: #f1c232;">Alliance </span></span></b><br />
<br />
<b>U-100</b><br />
<b>U-110</b><br />
<br />
The U-100 and U-110 are more or less identical units. Made in USA, they are well built, and feature worm gear drives. 4 Wires. The worm gear drives are desireable in these units, they are more precise and stout than all the others here. However these units have two peculiarities. 1, they are only adjustable to every 5 degrees or so, and 2, the controller boxes make an annoying clunk-clunk sound as they turn. Fairly commonly found on eBay, and available new from Norm's Rotor Service.<br />
<br />
Here is a video which demonstrates...<br />

<br />
<br />
<b>T-45</b><br />
<br />
The Alliance T-45 is a manual control unit, with a sturdy rocker bar, used to rotate the antenna. Its not as nice for television use, because 1 revolution on most all rotors is once per minute. The automatic dials are preferable. It is 5 wire and has worm gears like the U-100 and U-110 above. The rocker bar is nice, as it allows for precise control for zeroing in on a signal. Unlike the U-100 and U-110 above, this unit is infinitely adjustable. Uncommon on eBay.<br />
<br />
<b><span style="font-size: large;"><span style="color: #f1c232;">CDE</span></span></b><br />
<br />
<b>AR-22</b><br />
<b>AR-33</b><br />
<b>AR-40</b><br />
<br />
This is the classic TV antenna rotor series from Cornell Dubilier Electronics. The AR-40 is still in production by Hy-Gain. High quality rotors. One interesting aspect of these, is that they are not offset rotors...the masts, above and below come into them in a straight line. 5 wires. Fairly common on eBay.<br />
<br />
<b>TR-44</b><br />
<b>CD-44</b><br />
<b>CD-45</b><br />
<br />
These are a bit more stout than the AR series, which means they can take more weight and wind loading. These are 8 wire units. Fairly common on eBay.<br />
<br />
<b><span style="font-size: large;"><span style="color: #f1c232;">Channel Master</span></span></b><br />
<br />
<b>9515 HD (Heavy Duty)</b><br />
<br />
These are very rare. A sturdier version of the 9510A below.<br />
<br />
<b>Colorotor 9510A</b><br />
<br />
The CM Colorotor 9510A is made in USA. The RadioShack/Archer rotors below are the same units, under different branding. 3 wire. These are preferable to the new Chinese made Channel Master rotors (which are seemingly branded by everywhere). The older style controller boxes are a bit more hefty and solidly built. You can also use these with the newer 9537 remote controlled controller boxes that ship with some of the newer Chinese made models. Pretty commonly found new old stock on eBay.<br />
<br />
<b><span style="font-size: large;"><span style="color: #f1c232;">Gemini</span></span></b><br />
<br />
<b>Orbit 360</b><br />
<br />
Also known as the OR-360, and Gemini is affiliated with Philips. These were made in the US and sold in Walmart in the 1990s and early 2000s. Discontinued now, you can still find them used and new old stock on eBay sometimes. Pretty good little units, though not as stout as the CDE and Alliance rotors recommended here. 5 wire connection. I use this personally. Uncommon on eBay.<br />
<br />
<b><span style="font-size: large;"><span style="color: #f1c232;">Radio Shack & Archer</span></span></b><br />
<span style="color: #f1c232;"><br />
</span><br />
<b>Archerotor</b><br />
<b>1225A</b><br />
<b>1225B</b><br />
<br />
These are clones of the Channel Master 9510A, see above for details. Pretty commonly found new old stock on eBay. 3 wire.<br />
<br />
--------<br />
<br />
The Alliance HD-73 and TailTwister TX2*, Yaseu G450A, CDE Ham M, II, III, IV, and V series are good as well, but are a bit more expensive generally, and are overkill for television antenna weight and size.<br />
<br />
18 gauge solid copper core wire should be used for runs over 100 ft, 20 gauge is fine for under 100 feet.<br />
<br />
Thrust bearings are available to allow the use of taller masts with these rotors. There are 2 types.<br />

<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://i302.photobucket.com/albums/nn88/EscapeVelo/EscapeVelocity%20Blog/Tricraft300.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="400" src="http://i302.photobucket.com/albums/nn88/EscapeVelo/EscapeVelocity%20Blog/Tricraft300.jpg" width="256" /></a></div><br />
An unusual design is incorporated in the folded dipoles of Tricraft models 300 and 500 (above and below). As shown above, the model 300 antenna consists of two dipoles, a thin one cut for 70 megacycles and a thick one cut for 128 megacycles. The thick member is connected to the thin dipole by inductive rings, the latter connecting to the midpoints of the long 70 megacycle dipole. These rings act to end feed the shorter dipole, besides which they also act as supports for the thin section.<br />
<br />
When this antenna is used to bring in the lower channels, it behaves as a broad band folded dipole which is resonant at about 65 megacycles, the inductive rings acting as couplers of the two antennas and making them act as a folded dipole unit. At the higher channels, the long thin dipole becomes a wavelength and a half antenna, but the short antenna, being end fed by the inductive rings, establishes and in-phase relationship between the two dipole currents. This raises the radiation resistance of this antenna at the higher channels to a value much greater than it would be for a regular low band dipole working at the higher channels. Thus, a substantial match between antenna and transmission line is maintained for both high and low band reception when using 300 ohm transmission line.<br />
<br />
<br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://i302.photobucket.com/albums/nn88/EscapeVelo/EscapeVelocity%20Blog/Tricraft500.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="http://i302.photobucket.com/albums/nn88/EscapeVelo/EscapeVelocity%20Blog/Tricraft500.jpg" width="308" /></a> </div><div class="separator" style="clear: both; text-align: center;"><br />
</div><div align="left" class="separator" style="clear: both; text-align: center;">The Tricraft model 500 antenna is similar in construction, except that the long thin dipole section is mounted in a vertical position. This model is designed for mounting outside a window or porch in those instances where roof installations are not feasible.</div><div class="separator" style="clear: both; text-align: center;"><br />
</div><div class="separator" style="clear: both; text-align: center;"><a href="http://i302.photobucket.com/albums/nn88/EscapeVelo/EscapeVelocity%20Blog/Tricraft1000.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="http://i302.photobucket.com/albums/nn88/EscapeVelo/EscapeVelocity%20Blog/Tricraft1000.jpg" width="296" /></a></div><br />
The Tricraft model 1000 antenna (see above) uses a pair of parasitic reflectors with both a near- and far-spaced reflector. This antenna has a rated 10 dB gain on the VHF high band and 5 1/2 dB on the VHF low band channels, with unidirectional pattern at the same angle on both the low and high band. Although a number of minor lobes are present on the high band a single lobe is made to dominate in the desired direction.<br />

Antennas are spaced a half wavelength on the VHF low band and fed with 300 ohm line at midpoint. This antenna (see above) has a gain of approximately 3 to 5 dB, depending on frequency.</div><div class="separator" style="clear: both; text-align: center;"><a href="http://i302.photobucket.com/albums/nn88/EscapeVelo/EscapeVelocity%20Blog/Tricraft400.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><br />

<blockquote>What the heck is it? Brilliant Pebbles is a unique and comprehensive system for tuning the room and audio system based on special physical properties of highly symmetrical crystal structures. Brilliant Pebbles has been evolving since its introduction 6 years ago at the London HI Fi Show, especially the number of applications, many of which were discovered by our customers. Brilliant Pebbles addresses specific resonance control and RFI/EMI absorption problems associated with audio electronics, speakers and cables, as well as acoustic wave problems associated with the listening room boundaries and the 3-dimensional space within the boundaries. Brilliant Pebbles comprises a number of precious and semi-precious stones (crystals) selected for their effectiveness. The original glass bottles for Brilliant Pebbles have been replaced by clear zip lock bags, which have a more linear response than glass. We employ a number of highly-specialized, proprietary techniques in the preparation/assembly of Brilliant Pebbles to enhance the crystals' inherent characteristics. The fundamental operating principle of Brilliant Pebbles involves a number of atomic mechanisms in the crystals.<b> </b></blockquote><div class="separator" style="clear: both; text-align: center;"></div><div class="separator" style="clear: both; text-align: center;"><a href="http://www.machinadynamica.com/mikro-pebbles.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="267" src="http://www.machinadynamica.com/mikro-pebbles.jpg" width="400" /></a></div>Unknownnoreply@blogger.com1tag:blogger.com,1999:blog-6480652401120937590.post-38141076614295347852010-02-03T22:01:00.003-05:002010-02-03T22:29:48.522-05:00Cool Site of the DayCheck out gear and antennas from yesteryear!

CES 2010<br />
<br />
LAS VEGAS — Here are some of the home and portable radios that dealers will find in the booths of suppliers or in the booth of HD Radio developer iBiquity: <br />
<br />
<b>Cydle</b>: The company, an Asian OEM, is bringing out its first branded products, all with FM-only HD Radio and analog FM. The products are an MP3 player, a portable media player (PMP) and a portable navigation device (PND). <br />
<br />
The P15 MP3 player features 2GB embedded memory, rechargeable battery, antenna in the headphones and an armband. The P29 PMP features a 2.9-inch capacitive touchscreen, 18 station presets, and a gravity sensor to rotate display automatically into landscape or portrait modes, but only for video viewing. Other features include photo viewer, voice recorder, alarm clock and rechargeable battery. Its target price is $99. <br />
<br />
<b><a href="http://www.radioshack.com/graphics/uc/rsk/Support/ProductManuals/3100134_PM_EN.pdf">RadioShack Auvio</a></b>: The retailer's first component HD Radio tuner is a 17-inch-wide component bearing the Auvio house brand and due around International CES time at an expected price of no more than $99 on an everyday basis, iBiquity said. It features digital AM and FM and joins Best Buy's currently available component HD Radio tuner, available under the chain's Insignia house brand. <br />
<br />
<b>RadioShack Gigaware</b>: The retailer's second Gigaware HD Radio add-on for iPhones and iPod Touches is an FM-only model like the current model but takes on a different form. The new $69 model consists of a 0.25-inch by 1.5-inch by 1-inch tuner-embedded dongle that snaps directly into the iPhone and Touch multi-pin port. Headphones plug directly into the dongle. All HD Radio controls are accessed via a free downloadable iPod/iPhone app. The only control button on the dongle is an iTunes tagging button. <br />
<br />
RadioShack's current $79 add-on consists of a tuner embedded in an in-line navigation controller, which connects via cable to a dongle inserted into the iPhone. A 3.5mm jack on the other side of the controller connects to headphones. It also uses a free downloadable app to control the tuner via the iPod/iPhone touchscreen display. <br />
<br />
Both models use the headphone's cable as an FM antenna and feature iTunes tagging. <br />
<br />
The new model will ship as soon as it's certified by Apple, iBiquity said. <br />
<br />
<b>Sangean</b>: Two headphone-type tuner-only portables, both with HD FM radio, will be the first two HD Radio portables announced with AM tuner. One model features analog AM tuner chip, and the other features analog and digital AM tuner. Both feature LCD displays. <br />
<br />
The model with analog AM is available for shipment. Pricing was expected to be $99 or more, iBiquity said. The model with AM HD Radio tuner, due in the fall, will be the first portable with a portable digital AM/FM IC, iBiquity said. <br />
<br />
In another development, an HD Radio add-on accessory for iPhones and iPod touches was expected to turn up at the show, joining RadioShack's $79-everyday Gigaware-brand add-on. Both feature FM tuner and iTunes tagging. The accessories company developing the products did not want to publicize the product, however. <br />
<br />
<b>Sherwood</b>: The 7x50-watt RD-7405HDR A/V receiver, at a suggested $219.95, features digital AM/FM HD Radio, HD2 and HD3 reception, display of station-broadcast artist and song IDs, 7x50-watt amplification (with no more than 0.1 percent THD into 6 ohms), two HDMI inputs and one HDMI output, 30 radio-station presets, Dolby Digital and Dolby Pro Logic IIx decoding, 192kHz/24-bit DACs on all channels, and multisource dual-zone capability. <br />
<br />
Also at the show, another HD Radio dongle for the iPhone was expected to be displayed by an accessories supplier, but the company did not want to publicize the device.<br />

The first 2 books have multiple revisions, new editions, and are really ham radio oriented.. I generally favor older versions of these books, as they were a lot simpler, back in the day.

On the road, Surfin' views the world of radio through the windshield<br />
<br />
<blockquote>excerpt... </blockquote><blockquote>Last week, I wrote how as a ham, I see radio everywhere. I cited, for example, spotting ham radios in motion pictures that I happen to be viewing for entertainment -- not for their ham radio content.</blockquote><blockquote>I am not alone. Some Surfin' readers wrote to say that they also view the world through radio-colored glasses.</blockquote><blockquote>One reader reminded me of a facet of radio-spotting that I do so automatically that I do not even think about anymore. In his memory-rattling comment, he wrote, "I am often reminded by my wife to watch the road as we drive along when I spot an interesting antenna on a house or a hill."</blockquote><blockquote>I am in the same driver's seat whenever I am on the road. You probably are, too. I am always making mental notes of new antenna installations that I spot during my travels.</blockquote><blockquote>It never gets old. Every day during my morning commute, I skirt West Peak in Meriden, Connecticut; this hill spots an impressive collection of antenna farms resting on its crown. Depending on traffic, I try to sneak a peek to admire the hardware installed up there.</blockquote><blockquote><a href="http://www.arrl.org/news/features/2010/01/29/11313/"><b>continued</b></a>...</blockquote>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-6480652401120937590.post-56385915519630204902010-01-30T14:26:00.004-05:002010-02-03T22:35:05.278-05:00Cool Site of the Day<b><a href="http://earlytelevision.org/">EarlyTelevision.org</a> </b><br />
