A 30% tuner loss is huge and would be dissipating 500W of a 1500 watt input in a closed space. That wouldn't take long to set it on fire internally, and would quickly make it too hot to touch. On the
The ones I have seen came sealed in a little plastic baggie with a piece of paper (instructions) in it. The baggie made sure you got all the parts. Who you get them from? 73, Guy --. .-.. Guy Olinger
This seems to be one of those degree of effect things. Model ling of plain (no traps, no bends, no loading, no 4 inch element separations, just aluminum tubing, etc) elements and their combinations h
You HAVE a 34A. Put it up with your dipoles. DON'T use old coax. Pay attention to numerous articles about how to deal with cleaning/preparing old beams, weather-proofing, burying, routing, lightning
The Gap uses a coax trick to simulate a center loading inductor. It has been reported that off-resonance, high power has done some arcing and melting. It has nothing to do with the tuner, except that
Sorry to take this long to write. A phone call would be a lot easier...and I could tell you some stuff I will never put to a permanent medium. I have posted this to towertalk because it seems a recur
Get a crane. How will you explain to your grieving family that to skimp on a few bux, you risked your life or health on a rickety tower. Treat this just like a big dead tree that is going to fall on

The new F12 40's are designed to go over or under a tribander, rather than a WARC beam. Think the new "N" elements have a secondary resonance around 18 mHz, to keep it out of the hair of 15 meters in
First, the only one who REALLY knows about a WARC 2/2 over a C36XR is Tom at Force 12. Send him an email. There's a reason for that...in general this combo question involves transmitting on 15 or 12
TERRIBLE, TERRIBLE idea. DON'T do it. GUARANTEED to destroy both tower and chimneys in a big windstorm, and probably do a lot of damage to the roof below. Chimneys are designed to set on their own we
I found that the best approach was to use the mininec ground and place a resistive load at the ground end which can be varied. You may find that anything in a range behaves mostly the same or complet
Chimneys are notoriously bad places to mount antennas, be that TV or ham or ... Unless the condition of the chimney is new, and it is built very robustly, chimneys have been taken down by ice and win
Truthfully, a large tribander up on a mast will exert a considerable force sidewise in a 75 mph wind. If you have properly sized the mast for such an antenna even in a minimal wind zone, the vertical
I know of instances where the smaller wire (#4) was vaporized by a direct strike. In one case the destruction was underground, and the ham in question was without a ground for his tower until he was

Modelling getting good enough to handle a lot of things that can barely be measured. Unbroken wires 20' below a tribander can be either trivial or totally screw up the pattern, depending on lengths.
We possibly into this pink db, green db thing? Doesn't K7LXC practice dbd ala Force 12, etc? If the 1.3 db referred to db is over a dipole at similar height, we are not talking about a lot of loss. W
