Thank for info!

I forgot to mention that the boat is all metal (aluminum). You stated that
the strap should be short! my intent is to place the tuner three to four
feet from the antenna and mount it exposed to the elements on the roof.

Any problems other than Dacron Guywires need when mounting on an aluminum
roof? Also on near by will be other RF cables for Weather Fax and VHF,
where as my GPS and Radar are 14' away!
