In my opinion, high q loading coils are a much better loading method than linear wires. FWIW, full sized 30m elements are pretty manageable and it's quite easy to homebrew a rotating dipole. The issue with salt spray, at least in Aruba, is the dissimilar metal corrosion between stainless steel and aluminum. Unfortunately this is difficult to avoid. Perhaps covering the connections with a non-acidic caulk helps.

I have a12 year old Force12 30M linearly loaded dipole. It works fine when the local sea air doesn’t cause the loading wire connections to corrode making the antenna unusable. I’m tried of needing to repair the antenna every few years!

I’m considering a JK301 that uses loading coils and should be much more reliable. If someone has any experience with this antenna, I would appreciate any comments. The JK Antenna website doesn’t show any access to the assembly manual that I would like to see before any purchase. I have made a request for the manual from JK Antenna but so far no response.

Thanks es 73,
