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.

Subject: [TowerTalk] Weatherproofing for copper coils?
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 directly to the
copper tubing rather than construct housings for the coils.
Heat shrink tubing seemed a possible solution but finding the right
combination of UV resistance, low RF loss, and price has been
unsuccessful. (PTFE heatshrink has good properties but runs almost
$2/foot.)
Are there any low loss paints or coatings that adhere well to copper
and can withstand a north Texas environment for several years?
Any suggestions on how best to weatherproof the coils is welcome....
Steve
