[TowerTalk] Shack wiring

[ny6dx at netscape.net]

Pete,
   Check the voltage at your panel and see if it low there.If so it is power company probles.If not increase the guage of your wire feeding you circuit.If using a 14 gauge go to 12.Rule of thumb is to increase wire size for ever 100ft to compinsate for voltage drop.
