Some time back K5RC made a posting to Tower Talk regarding station cabling and why not to use Radio Shack-style cables. I'm in the process of re-wiring my station, with the hope of eliminating the ra
Maybe it's me, but I'm having trouble understanding how the coils fit on a Sigma 40 vertical. Force 12 says it's simple, but that's all they'll say. When I tried to put it together as per the instruc
My family and I are just back from 2 weeks in China, about 1/3 was spent in Shanghai with friends. For a city this large (17m people, we were told), where you drive -- well, sit in traffic -- to go j
I've just inherited approx. 50 feet of RG-142 that I'd like to break up and use as jumpers in the shack. What connectors are available for this double-shielded coax, and how hard are they to put on?

After this wekends dismal performance on 80 and 40, it's obvious that I need something better for those bands (not to mention 160). N4XX published an interesting design in January's CQ Magazine that
I'm thinking of replacing my existing short roof quadpod with a taller one to raise my C-3SS higher off my roof in order to (hopefully) cure some interaction issues. I have two routes to go: a Glenn
Looking for recommendations, comments, thoughts on the following: I want to raise my roof-mounted C-3SS to get it away from possible interaction with my roof. It's about 6 feet over the peak. If I hi
Just as G0JHC was looking for pictures of roof mounted antennas, so am I. What I'm looking for is a picture or pictures of (peak) roof mounted Rohn 25 tower (with top shelf) and a modest sized triban
Need some sagely advice for my spring/summer (should it ever get here!) antenna project, one that I'm planning to do with local help, raising my C3-SS ~6 feet higher off the roof. I can go with eithe
I've been hearing rave reviews for open wire fed antenna systems and am interested in trying them myself. My question is quite simple...how do I get the feed into my basement shack? Thanks in advance
