Good Morning on this Memorial Day. Came across a duplexer brand called "Intermod" model Model: D440N-4, made in Canada, for what seems to be a great price (about 268.00 USD). I am seeking input from someone knowledgeable about what is considered decent parameters as I just don't know. Below is what is listed... Electrical Specifications Frequency Range MHz 406 to 470 Return Loss(min) dB 18 Insertion Loss(nominal) dB 0.6 Isolation(nominal) dB 80 Impedance Ω 50 Tx-Rx Separation (*) MHz 5 Average Power Input (max) W 100 Thanks in advance, Scott

I just purchased the same one. Pretty good so far. 50watts in 43watts out. 80db of isolation is just as good as my 4 big cans decibel vhf band pass/band reject duplexer. Very impressive. I like the use of silver plating. Nickle makes a mess out of tx'n uhf. Great construction and size.
