Richard: I still vote for adjusting the shunt cap for minimum reactance, then the series cap for 50 Ohms. This will likely be an iterative process, so be patient. 73 de Gene Smar AD3F Weather Station
TT: At the electric utility where I designed substations, we used galvanized braided cable to connect moveable parts to our ground grid. These places included swinging chainlink gates connected to th
Don: Regardless of what folks tell you about lowering the tower, do NOT use the chimney as a pulley support. Chimneys might not be part of the house structure. One of my summer jobs in college was fo
Keith: Try http://www.harger.com/productinformation.htm . I bought my #2 solid tinned copper ground wire and misc. connectors from these guys four years ago. Really good people to work with. 73 de Ge
Bill: Before you start pulling your hair out and dismantling all the work on your antenna, answer this: Is there an AM broadcast station serving your area? The MFJ259's are notoriously finicky in the
Bob: There have been postings here on TT about the correction factor required for dipoles when constructed with insulated wire. Most sources showed a 3-5% shortening when PVC insulated wire was used.
JT: I haven't posted any pix yet, but you can check the frequent postings I made to TowerTalk during my tower's planning and construction period in mid-2001. Below are a few directly describing this
Warren: I made my own coax shield grounding connector and posted something about this a few years ago: http://lists.contesting.com/archives//html/Towertalk/2002-07/msg00698.html . My approach gives y
Richard: Congratulations on the success with your shunt-fed tower. Welcome aboard! Regarding a wire for 80M, if I hadn't suggested this to you before, here it is: a half-sloper wire hung off your tow

Kelly: Around here (DC area) that's known as a Georgia Buggy. But be careful. I rented one for my tower and found that it bounced around pretty much when empty. Never needed it for the pour (truck dr
Larry: Off-the-top-of-my-head list: 1. Proximity of grounds (electrical service close to cable TV close to water pipe close to phone close to shack close to etc.) 2. Laying of ground ring around home
Alan: I ran into the same issues when installing my coax grounds on my tower. The most vexing to me was the price for commercial straps. So I devised my own using copper flashing and posted here on T
Bill: I believe this month's issue of QST (Nov) features a wire Yagi for 80M that uses coax on the outer elements to switch from director to reflector as required. A short length of coax is permanent
Gary: I have one of these baluns in the workshop. Used to use it to feed a 30M inverted V, but took it down a few years ago. The lightning arrestor/suppressor is nothing more than a thin piece of alu

Hector: Many folks have asked on TowerTalk in the past about using coax for shortened ground radials, using the VF to shorten the required length. That doesn't work. The VF is important only when usi
