[Antennas] inline female coax connector?

Jack- ALL the DATA I have seen reported about UHF connector losses has been 
less than 0.1 dB, not in the order of 0.5. By data, I mean measured values, 
not manufacturers "specs". There have been several sets of measurements 
that support this, and even lower values. The "UHF" connector is really 
pretty good.
I use connectors only where I need them, such as bulkhead feed-though, 
cable type transitions, essential disconnects, ground points, etc.
You are free to be as anal as you wish, but when you can report data on the 
subject, with methodology, I will listen, and put it in with the others I 
have seen. The same goes for the use of N connectors at 70cm or below. (An 
N connector is no more than a BNC surrounded by a massive metal sleeve)
