It is very standard to use the back stay guy of the main mast for antenna on a sail boat. It works very well, if the boat has an adequate ground plate and bonding of the metal of the craft to radio ground. Metal towers used with slopers are no different from a metal mast and a slanted back stay antenna wire. They work lots of DX. Most of the 20m maritime net folks use a version of this system, and have good signals into USA from their sailing locales.
Yes, take your K2 on a sailboat and you can use the back stay by insulating it, and feeding it with one of the random wire tuners. The k2 tuner may well work fine for 20m and up depending on the length of the backstay. 72, Stuart K5KVH _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
