· You may have problems going all the way down to MHz using this duplexer. I have used the same basic design on a commercial 25 watt output repeater in the / MHz range and it worked fine with the 5 MHz split. However, it didn't like going much below around MHz. Glen, K9STH.

Celwave VHF Duplexer Model Mhz Quantar MTR HAM Description: You are bidding on a Celwave/ Radio Frequency Systems(RFS)VHF Duplexer model number this duplexer can handle frequencies in the Mhz range with a max power output of watts. These units have a MIN Channel spacing of Khz. FD FD FD Rx Frequency, MHz: Tx Frequency, MHz: Rx Insertion loss, dB: Duplexers isolate RF transmitters and receivers connected to a common RF line or antenna. A Duplexer passes transmitter power at one frequency while preventing it from reaching a receiver tuned to a different one. Signals propagating at the receiver frequency are blocked from reaching the transmitter.
Retune duplexer to new frequency pair and test. Celwave UHF Duplexer, S/N: Retune and test duplexer. Motorola UHF Duplexer, STN: A Fine-tune and test duplexer. Celwave UHF U05 UHF Duplexer, S/N: Tune and test duplexer, with more in-depth Smith Chart impedance testing. Motorola relabels the Celwave model PD duplexers and includes them as factory option with VHF Quantar or MTR stations. Their part numbers are U01 for the MHz range, U02 covers MHz, and U03 covers MHz. PD VHF Duplexer tuning info from RFS/Celwave kB PDF file. Duplexers isolate RF transmitters and receivers connected to a common RF line or antenna. A Duplexer passes transmitter power at one frequency while preventing it from reaching a receiver tuned to a different one. Signals propagating at the receiver frequency are blocked from reaching the transmitter.
