[Collins] RF connectors for 312B-4

[Dr.Gerald Johnson]

Don't think you CAN change those connectors without destroying the 
directional wattmeter and its calibration. 

The mating connectors are a standard type N easier to put on coax than 
the PL-259. The right angle adapters for type N and right angle N connectors 
are available from several vendors including Digi-Key (www.digi-key.com) 
and Mouser (www.mouser.com) There are also adapters that convert from N 
to UHF if you must use the mismatched and hard to install UHF connector.

UG-146U is the N to UHF adapter.
UG-1185/U are the better straight N connectors.
UG-27A/U are the N right angles.
The only right angle plugs I'm finding in the catalogs are outrageously 
expensive and require a crimper. The right angle adapter and straight plug 
are more practical.

I often find these at hamfests and surplus stores. My stock is in use or 
planned for use and not for sale.
