The RMS voltage for 1000 watts into a perfect load is <250 volts. I  
suspect that Tony's 4,000 voltage limit is closer to what a quality  
PL-259 can actually handle. If the PL-259 is arcing, there is  
something very wrong with either the connector, the weatherproofing or  
the antenna.

Walter,
Yes, the UHF connector may be rated at 500V, but in practice they  
handle >4KV. The voltage limit is set by the air gap between the  
center pin and the shield. I have not had a PL-259 arc over.

Even with a 1:1 SWR, 1000 W is pretty close to the 500 V peak rating  
for a UHF connector. Type N connectors are rated at 1500 V peak.
