1. [Towertalk] 100M-long boom Yagi for 20M (score: 1)
Author: af4mp@mindspring.com (Zyg Skrobanski)
Date: Sun, 12 Jan 2003 11:09:09 -0500
A typical broadcast curtain array will have a gain of 21 dBi with a bandwidth of about 10°. I guess that's why super long Yagi's are not used. I'm waiting for some fancy contest outfit to come on

Curtain arrays are available in many shapes and sizes. The 21DBi gain model is just one example (as a comparison with the super long yagi). They are basically a bunch of stacked (vertically and horiz

Yes, of course, but we are talking about fancy set-ups that have no concerns about real estate. Not exactly your average suburban lot! -Zyg- AF4MP -- Zyg AF4MP Roswell GA USA

The rotatable curtain antenna (refer to URL below) is exactly what is needed! http://www.antenna.be/rhr.html No serious contester should be without one. -Zyg- AF4MP

Interesting - as I'm just about to install a guyed tower with 500D insulators breaking up the 3/16" guys. Texas Towers web site gives the price for a 500D insulator as $2.95, and 3/16" cable clamps a

OK; but what did people do, not so long ago, when grips were generally unknown to the ham community? Were all those clamped insulator installations unsafe? There didn't appear to be a spate of tower

Last time I checked, curtain arrays were way more directional (and consequently had more gain) then yagis. -- Zyg AF4MP Roswell GA USA

If you are concerned about the length of the antenna, and are going to operate at output powers of 100 watts or less, then have a look at the Comet CA-HV antenna. It provides two band HF operation pl
