Re: UHF Cans?
They are Telewave VHF pass cans. Most likely from a Telewave VHF transmit combiner. Most older wide space transmit combiners used simple pass cavities. 73, Jim W7RY -- Thanks and 73, Jim W7RY

Re: UHF Cans?
They look like the ones used on 900 Mhz paging transmitters. Probably tuned around 928 - 932 Mhz. Will handle a lot of power.

Re: VHF MTR2000 Poor Receive Performance
Measure test cable losses by replacing the tee with a female-female barrel, then correct your insertion loss measurements based on that value when you¡¯re adjusting the coupling with the tee
