[TowerTalk] JK301 30M Dipole

[john at kk9a.com]

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,
