I wonder what the cost of silver plating the coils would be? I guess you would have to be certain that the coils are built correctly before you would take them to be plated. Tod, KOTO Towertalkers, I
Hi Steve, You might consider building yourself a hi-q parallel resonant tank circuit that you can put in parallel with a dummy load. This will allow you try various coatings and compare for self heat
Towertalkers, I am upgrading Cushcraft 402-CDs. The plan is to replace the stock loading coils with high-Q coils made from 1/4 inch copper tubing. I'd prefer to apply a low loss protective coating di
I can't answer this question, but it brings up a question I had about upgrading two of these antennas myself. I am contemplating doing the same since they have become intermittent. My question is wil
UGGGGH! Why re-invent the wheel? This is a 20 year old, PROVEN, antenna. Plenty of articles tell you how to solve the problems you guys are asking about now. Why not just follow them? Go to Leeson's
Reinventing is what it's about! That old design was produced to be cheap, that's why you had to rebuild yours. I'm sure the electrical design is not optimized either. My question is simply to those f
A little additional clarification. I haven't modeled this yet but are the inductors deliberately lower Q, read "higher loss" to add some "R" to perhaps 1) improve SWR bandwidth and F/B and/or 2) brin
