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

[Bill Steffey NY9H]

While I started using BNCs on my receive only connections, like a second 
receiver output for the Omni 6+ , I also have been using them for Xmit as well.
Their convenience of quick disconnect beat the UHF & N connectors.
While I pick up the constant impedance advantage, I'm not certain of their 
continuous power capability. I use UHFs & rg 213 for the output of my Herc 
& Titan. So do any of my esteemed colleagues have an idea of whether the 
BNC is beyond its ratings for 100 watt use ???   bnc= (bayonet-neil consen)
Thanks in advance
