1. TopBand: 160m shunt feeds (score: 1): Author: k6se@juno.com (Earl W Cunningham); Date: Tue, 29 Jul 1997 03:21:55 EDT; Hi, all: After reading some of the comments on shunt-feeding a tower on 160m, I thought I'd put my 2 cents worth in. Bob Kile's (KG7D) comments were quite interesting, but I felt that his mention abo; /archives//html/Topband/1997-07/msg00109.html (10,363 bytes)
2. TopBand: 160m shunt feeds (score: 1): Author: k6se@juno.com (Earl W Cunningham); Date: Tue, 29 Jul 1997 13:05:42 EDT; == I've never really measured the 1/4-wave self-resonant freq of my towers. My assumption is only based on experience and ON4UN's chart on page 9-43 of his excellent book, "Antennas and Techniques fo; /archives//html/Topband/1997-07/msg00113.html (8,277 bytes)

For those of you with antenna modeling software, this is an excellent way to estimate the resonant frequency of your; /archives//html/Topband/1997-07/msg00114.html (8,591 bytes)
4. TopBand: 160m shunt feeds (score: 1): Author: midnight@accessnv.com (Robert Kile); Date: Tue, 29 Jul 1997 11:06:57 -0700; In response to questions. I use short aligator clip lead with 1-2 turns on GDO coil to find the 1/4 wave resonance which is the lowest frequency that you will get dip in meter.

5. TopBand: 160m Shunt feeds (score: 1): Author: midnight@accessnv.com (Robert Kile); Date: Tue, 29 Jul 1997 11:19:50 -0700; Guys, Earl's points are quite valid. Anything will work. To work better there must be a topcoat on the shortened tower. To perhaps make myself a little more clear with respect to resonance.

TopBand: 160m shunt feeds (score: 1): Author: km1h@juno.com (km1h @ juno.com); Date: Wed, 30 Jul 1997 11:56:26 EDT; Although it obviously radiates Bill, I question the efficiency of a #12 wire 4' away from a large tower cross section. Do you have anything to show that this is a correct d1/d2 ratio and spacing? It; /archives//html/Topband/1997-07/msg00132.html (9,513 bytes)
