[TowerTalk] guage of wire for 500 watt antenna?

[john nistico]

Gary 14 gauge will more then handle 500 watts. Tell me how much wire you need and I'll donate it seeing I'm an electrician I have plenty laying around

(I use either gauge 14 or gauge 12 for all the wire antennas at my qth).  If the antenna survives then you know that you are ok.  If not, then you may want to go with a heavier gauge.  Although there won’t be ice and snow in Belize, there will be wind, rain and flying debris if it gets windy enough and you want your wire to be strong enough to survive without breaking.  You want the PVC coating on the wire to reduce the effects of abrasion, corrosion by salt spray and to reduce the rain noise on your antenna.

I will be at a friends house and not next to the ocean so I'm thinking of getting a doublet up in the air as far as I can on a fiberglass pole, feeding with 450 ohm ribbon and tuning it on 10 thru 40 and maybe 80M.
