Hi guys,
OK on everything BUT one, waterproofing all outdoor connections. While the F connector itself may be water tight the adapter and antenna connector are not. OK, I'm stating the obvious but YOU didn't. (;->) A good tight, stretched wrap with vinyl tape starting about 2" below the fittings, up to cover the antenna connector completely and back down to the start finising with a non-stretched turn will do the trick. The reason you don't stretch the last turn is because the tape shrinks again and while that draws it tight that last turn will become loose and flap in the wind. If you want a bit of overkill Tommy Tape used in marine applications is about the best sealant you can get for such purposes.
Woody, considering you'll have to use an adapter and seal it, a weather resistant F connector is a moot point.
"I would still use a good 50ohm coax on the Discone unless there was nothing but RG-6 in the entire state."
PRC, we've gone over this a thousand times, for a multitude of reasons 50 or 75 ohms doesn't matter a bit! Signal loss is much more of a consideration and for two reasons RG-8U, RG-8X or RG-6U doesn't matter either, they have just about the same dB loss and for a 30' run it's insignificant. RG-8AU polyfoam has a slight edge but again for 30' it doesn't matter as long as RG-58U and RG-59U are avoided, they're good only up to about 30MHz except for very short mobile runs.
I always save the best for last;
"Solder is where you get loss on PL plugs if the coax center does not touch the PL."
Larry, you did it again. How can you guarantee the center conductor will touch the inside of the pin unless you're using RG-8U or equivelent cable? Since when doesn't solder conduct electricity? I could have sworn that's what it's used for but the military, millions of hams and I could be wrong. Whatever did we do before they made crimp on PL-259s? (;->)
