I bought some 6'x8" screw anchors thinking they'd go into the clay soil pretty easily, and they do...for about two feet. Then they hit rock; I am pretty sure it's bedrock or something similar from t

The coax connector shouldn't be hot! This implies an insulation breakdown in the connector. It doesn't happen at low power because breakdown voltage is not reached, it happens only on 15 meters becau

Kelly, a 10ft piece of 2" or so OD pipe or tube can be cut to three equal lengths, Then you can drill holes to match the tower legs and bolt them together. Probably best to use grade 8 bolts. The old

Conceptually this could be done using 50 ohm coax stub matching. Starting with the R +j of the four band segments, a design for each band series segment can be done. Then starting with the shortest s

I agree with Don. I did this years ago for a frame for a EME array. I could not get it to come apart if I wanted to. Mike Run a slit down the 2IPS40 pipe, compress it to get it in, then it'll expand

Quick, cheap easy and effective..... Go to a local muffler shop... Show them what you're trying to do... Let them put the tubing in their 'expander'....and bump it open slightly for the fit you need.

This is from a helmet mounted cam, tower workers removing the upper antenna from John Hancock building in Chicago. No fear of heights in these guys! Using a cutting torch even. YIKES! YIKES indeed.

It's the same thing with railroad cars, the electric systems are "floating" so a leakage to chassis can easily be detected. Hans - N2JFS 'grounding' in submarines was interesting... NOTHING was conne
