Speaking of Yaesu connectors, I just found a place where one can buy rotator cable with the Yaesu connectors already installed: http://www.randl.com/shop/catalog/index.php?cPath=7_11090 Be careful yo

ORIGINAL MESSAGE: (may be snipped) REPLY: I can perhaps explain it from my own experience. A quad large enough for 20 meters is a mechanical nightmare. Unlike a yagi, a quad is a three dimensional ob
ORIGINAL MESSAGE: (may be snipped) REPLY: One last thought on quads: Use only copperweld wire. Ordinary copper will start to break after 3-5 years and is a huge pain to fix. Copperweld is nasty stuff
ORIGINAL MESSAGE: (may be snipped) Actually, FT240 and similar part numbers were cooked up by vendors like Amidon and Palomar to keep the customer ignorant of the real part number, so that they could
ORIGINAL MESSAGE: (may be snipped) REPLY: Why not leave it as is and allow it to function as a lightning rod? Much better for a bolt to hit the mast rather than your antenna. 73, Bill W6WRT _________

Excellent idea, I wish I'd thought of it before I installed a molex connector. The ones I am familiar with have only four conductors but you could use two of them of course. The advantage over molex

I am modeling a full size ground plane with four elevated radials for 40 meters using EZNEC v. 3.0. I have it six feet above ground. I noticed that changing the length of the radials has much less ef

Some more results modeling HF ground planes with EZNEC. I took my existing 40 meter ground plane with a 33 foot vertical element and elevated radials at six feet high, which had a resonant impedance

-- ORIGINAL MESSAGE --(may be snipped) REPLY: You really need both good SWR and good patterns to have a good antenna. Sacrifice either one and you have a lousy antenna. A bad pattern will not harm yo
