[TenTec] BNC vs UHF connectors for HF 100w use

[cherry@getnet.net]

I have heated up both N and BNC connectors running high VSWR
at powers as low as 200 Watts. The UHF connector does have a 
larger center pin. I melted a RG-8 cable with 200 Watts at 10:1 
VSWR. I do not think much power was getting to the antenna.
