Jerry: Congrats on the achievement. Your first QSO on, let's say, 15M, probably wasn't as exciting or gave you the same thrill as this, I bet. Keep up the good work. 73 de Gene Smar AD3F ____________
Marty: I had an inv L for Topband before I built a self-supporting tower and shunt-fed it. For a while I operated both and did A-B comparisons on the air. The tower was 5-10 dB better than the L on T
The first Callbook? Especially interesting to see how the hobby grew each quarter by reading the Amateur callsign additions included in each supplement after the initial release. 73 de Gene Smar AD3F
Jerry: Here are a couple of poostings I made after I built my tower and shunt-fed it back in 2002: http://lists.contesting.com/archives//html/Towertalk/2005-12/msg00636.html . I did not install a sec
Jeff: I've done exactly what Herb suggested: hung a sloper for 80M off the side of my 160M shunt-fed tower. Neither antenna knows the other is there and both work pretty well - meaning I'm satisfied
Paul: My tower is a 64-foot tall Tryon self-supporter - shorter than yours. Top loading is provided by a Bencher Skyhawk ten-element triband Yagi where I shorted the parasitic elements to the boom wi
Joe: Don't ask questions and just enjoy the antenna's performance. 73 de Gene Smar AD3F I moved my 160 inverted L to a tall tree in my backyard to get more vertical height. The vertical leg is now ab
Paul: Congratulations! Just imagine the changes in technology that have occurred over that period of time. 73 de Gene Smar AD3F CONGRATS indeed Paul, well done there OM! 73 de Billy, AA4NU -- Origina
Gents: The shock one would get under such circumstances was one of the reasons that early studies into the effects of HV AC lines were flawed. I believe even Brodeur's work cited this erroneous work.
. I told my YF Hi guys You have both surfaced a topic that is of great personal interest to me as I have worked JA on 160m around 2100z both from K1ZM on Cape Cod and from VY2ZM on PEI many many time

Bob: I built my shunt feed wire cage based on the design in Jeff Bigg's K1ZM book "DXing on the Edge..." I bought it from the ARRL bookstore but you might be able to find it on Amazon, etc. I used tw
Bob: Here's a link to a link that has some photos of a shunt feed cage similar to mine: http://lists.contesting.com/archives//html/Towertalk/2005-12/msg00643.html. It's not really a "cage" but Phil h

Paul:\ Congrats on the milestone! You've seen much of the evolution of electrotechnology that has occurred in the 20th Century. Pretty amazing, that. I'm a newbie compared to you. I celebrated fifty
Doug: I have both types of antennas but on different bands. On 80M I use a half-sloper wire off the 64 foot tall tower tapped at the 55 foot level. I selected that spot on the tower because that gave
Doug: Wire-based antennas like the one you're proposing (and like the ones I have off my tower) are cheap. Build it and try it. You can always reuse the wire from the radials. As another suggestion,
