Terry, I used to have an 80m dipole that radiated the dump power from my 80m 4 Square. Dipole happened to be on edge of a drop off favoring NW where my 4 Square wasn't good because of all the towers
I don't know about putting it in the middle of the 4 Square. I wouldn't do that but shouldn't be a problem to run a coax to another antenna a hundred feet away it maybe even a flat dipole up as high
Just realized you weren't talking about putting the vertical inside the array. :-) _______________________________________________ _______________________________________________ TowerTalk mailing li
Gary, My first thought would be to cut off whatever length you would need of 25G tower, if it would fit over the post. If it would not fit, I would somehow shim 45G so it was tight after telescoping
Similar to what W7RY recommended but 2-1/8". Last time I bought any they were 2-1/8" because of too tight fit on 2". https://www.thebigbearingstore.com/2-1-8-four-bolt-flange-bearing-w-lock-collar-hc
I would make a trip to the CATV providers in the area and see if I could get free hardline, replace it with something less likely to ever have a problem, match the antenna to 75 ohms at antenna feed
Bruce, I haven't done this but believe an insulating tube over a pier pin and a sheet of insulating material attached to the bottom of a pier pin base with the hole in the base plate oversized and ho
Brad, Google "Greyline Map" or use N1MM 73...Stan, K5GO _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com
Scott, Not hex head screws. Socket head (Allen) cap screws instead. Outside perimeter of head is round. Big difference. 6-32 for 5/8" and smaller, 8-32 for 3/4-1-1/8" and 10-32 for larger up to about
The contest station at K5GO has been largely dismantled, and I am now going to offer for sale the big 40M antenna and tower. The antenna is 5 Elements on a 90 foot boom. The boom is 45G, the vertical
Dave, Not that a big concrete base is needed if you are going to guy the tower, but if you are digging a big hole and pouring concrete I would put another 25 feet of 25G in concrete, bracketed to the

Scott, Just my opinion, but even if your trapped Tribander had a good SWR and was brand new instead of 27 years old, I think it would be wise to purchase some aluminum tubing and build one from scrat
Dave, You should decide based on how much extra coax you have, the frequency band where it is being used and the extra loss as to whether you want to cut it or not. Certainly there is nothing wrong w
Tom, There is not a single thing about this installation that I like or would do if it were me. Stan, K5GO _______________________________________________ ____________________________________________
I am leaving this weekend for ZF and don't have a lot of time for experimentation. Just starting to focus on radio after 6 months of golf. Retirement is fun! I want to put a 40m dipole above a Triban
Thanks to everyone who responded. I think the plan is made Stan _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contes
Funny story - My dad, N5DX, (W5DRW at the time) was operating AM one Sunday morning back in the 1950's. Someone in the congregation at the First Baptist Church about three blocks away left the buildi
I am looking for ideas on something off the shelf or easy to make that would allow you to parallel multiple sets of up to eight wires using plug in connectors. Currently I am using a couple of Green
