Pat, I don't know what kind of winch that tower has, but when I replaced the Fulton 1550 on my LM-470 with a 2550, it was literally day and night. Previously, I would alert the local rescue squad bef
I have been using six band (6-20M) concentric quads for 15 years now and tribanders for double that. My current quad is a six bander which I modeled with EZNEC before building it. The actual characte
Thanks, John. Nice to hear from you again. You're the only one to get back to me on the subject. I was pretty sure that my guess about resonances was accurate, but wanted to hear the opinions and exp
A friend of mine, who was an E.E. and whose boss was a ham but who didn't think very highly of ham radio, referred to ham radio operators as "guys who talk on the radio and tell each other how big th

I am in the process of parting out my damaged LM-470 and in trying to remove the gear box, it appears that the shaft from the gear box is press fit into a collar on the winch drum. Is that really a p
My LM-470 was damaged in a windstorm about a year ago and has been since replaced by a new model. The primary damage was that the 2nd section from the top was bent over at about six feet up from its
I had full replacement insurance on my tower, antennas, etc. in NJ through NJ Manufacturers and now have it in VA through VA Farm Bureau. I had a claim in both cases. Premiums are still reasonable at
Mike, this stuff was being sold at Hamfests back a few years ago, and I believe it is military surplus. I bought two 80' rolls myself and am currently using one to feed an HF quad. They are 50 ohm an

I've done something similar to what Larry has done; however, I use heavy duty, flexible vinyl and fold it into a simple cone. I wrap the top of the cone around the mast above the thrust bearing so it
OK, Roger. Well, I have never lived that far north, but the vinyl cone worked for about 10 years up in northern NJ until I moved here to SW VA. If the vinyl is flexible enough at room temperature, it

Tom, do you want the impedance to be largely resistive so that it's not so frequency dependent and the ferrite is effective over a wider frequency range? Just curious, because I just bought a bag of
