Twist them up, and tin it. If you are melting copper, yup the heat is way too high. Even copper coated aluminum should not melt even close to the melting temperature of solder.

Buy yourself a good line isolator/choke/balun. In the past, I have had that to happen. All the power was not going out the antenna, and the coax was radiating too. Bought a Palomar Engineers Maxi-Choker 3K that fixed the problem. It was installed about 8.5 feet down below an Imax antenna...

Was going to post a "Come on man", but after reading the above, it's an attaboy!

Let me back up over the weight of this antenna. Don't want to misrepresent. Took it to UPS, and they weighed the box with all antenna parts inside. It weighed 10 lbs. 11 ounces. It's a very big, long, and thick corrugated box. I would estimate the box would weigh at least two pounds. That's...

Four big capacitors for a two transistor amp?

Hygain Penetrator is going back to DXEngineering. It will not tune period even after installing the base insulator the correct way. SWR stayed the same. Also, all four radials would not lock up good even with double clamps. I think that's the problem. There is no way this antenna weighs...

Just put one together yesterday, and it won't tune worth a dang. 22 ft 4 inches was the best SWR at 5.8 on channel 1. Tuning it with a RigExpert. Finally found this thread, and the base insulator is installed upside down from the factory. Hopefully, once I get the base insulator changed it...

Dang that's awesome. One V-Quad mounted 12 foot above the ground works very good. I know three would be awesome!

NPC mod that can be turned on and off plus all the other features. And I love the styling. I want one now!

I will be on Saturday for sure.

Even the crappy zinc coating stuff rusts way too fast. Apparently, they are using the thinnest coating possible. Fortunately, I can still get hot dipped galvanized hardware from the local hardware store that lasts for years and years. On the Imax I just installed recently, I used hot dipped...

To stay on topic. I am talking about why they would recommend lengths of coax that are half wave multiples. Not about some mistake in a patent. And, no, I don't believe every thing I read.

Went to Bojangles last week, and a 12 piece family was $37.99 plus tax which came out to be $40.65. Eight piece family was $27.99 plus tax. I drove off, and went home, and made sandwiches.

Just wondering why Avanti Specialists would recommend in their instruction manuals to use 12 foot multiples of sold dielectric coax(RG213), and 14 foot multiples of foam coax(RG8) if it did not matter? Snip of a Moonraker 4 manual.

Quad 6 for $218. Lincoln 2+$210. Free shipping. Thanks for the heads up!

Yes the power company has one of the gadgets like the cable companies have that check for RF interference. I have seen the cable company riding down my street, and aiming it out of the driver's window. It's like a small hand held Yagi antenna. Also, is there a cable amplifier near that pole...

Apparently you did not read, or comprehend the article, or cannot admit you are wrong.

Wrong! Will post a link to an NMB article that compares ball versus sleeve bearings. NMB is a top tier fan manufacturer. Ball vs. Sleeve: A Comparison In Bearing Performance http://www.newark.com/pdfs/techarticles/mro/ballVsSleeve.pdf

Another cheap Evercool sleeve bearing fan that should not be mounted horizontally. I have seen the same fan on Fatboy amps too.

Video on YouTube of the Imax 2000 that has been cut open, and explains what's inside of it. The extension is just a piece of wire inside to make the antenna longer. Nothing special about the extension...just makes the wire longer. www.youtube.com/watch?v=HuAiNXvBgA4 Then the same fellow made...
