[TowerTalk] Best UHF Connectors to install a top of tower

[Ben Horton]

Please excuse me if this has been hashed over before. I am going to 
install some UHF connectors to interface from a brass 7/8" Heliax 
conector to a RG-8 rotator loop (Bury-Flex) and on to an antenna balun.  
Also, going to interface to transient protection devices at bottom of 
tower using the same UHF connectors.  What type of UHF connector would 
be the best to use so that only one trip up the tower is needed for a 
long, long time? The ones I have found readily available are as follows:

UHF-182120 Amphenol-Connex. Silver plated body and shell with Teflon 
insulator

83-822, Amphenol, Teflon insulator

83-1SP, Amphenol, Silver plated body, Nickel Shell and LCP insulator

Would you please recommend one of the three above connectors and are 
there any interfacing problems with a brass Heliax connector and the UHF 
connectors?

Thanks for the help in advance.
