He'll get as far or further than the hundreds of RG58 installations I've seen. I was at least attempting to offer a helpful opinion rather than trolling. Eric Lowell Eastern Maine Electronics Inc. 48 Loon Road Wesley ME 04686 [email protected] www.satnetmaine.com 207-210-7469

If I were the vessel owner, I'd use a good grade (Belden or equivalent) of RG-8 (X if you want). There are not a lot of terrain features out there. I'd think you could talk quite a ways on 25 watts at 70 feet HAAT. 75-100 miles?

Keeping in mind that we are talking about a 70’ or so run going up the center of an aluminum mast, in a salt water environment, and the radio is limited to 25 watts. Also keep in mind that when off shore this is a life line and the best possible send and receive is needed in an emergency situation. So given the criteria what is the best possible coax to use knowing that thickness matters and bend radiuses may be tight? Others on the list are saying “just grab any old 8X type cable and you will be fine”. I say use something with very low loss and suggested small heliax. Any suggestions? Vern s/v Nirvelli KI4ONW
