Has anyone used this duplexer? Are there better products in this price range for a duplexer with a minimum frequency separation of 3MHz?

Check EMR. I've been extremely impressed with their products, price, and their willingness to work with their customers. You can even talk to a real live engineer (not an "engineer" - someone who actually designs these things). They've also turned new duplexers for me in less than a week when I've been in a bind (fire repeater down, old duplexer nuked by lightning), without any rush charge. Ordered Monday via credit card, delivered Friday.

What would you suggest? Something like the 64536/ENC?


Thanks for your help,

Let me peer into my crystal ball...

I can suggest a product if you want to provide the TX/RX frequency and input power. I'd suggest strongly looking at one of their Isoplexers (duplexer + dual isolator), as all transmitters colocated with other users should be properly isolated. The 64676/SNCI-2 is what I use on our fire repeater, and it works quite well, despite being a 515KHz split with another 100-watt transmitter on the site 300KHz off my input.

Sorry, I forgot to include that little detail.
Frequencies are 155.145MHz & 158.835MHz
Repeater will be 50-watts

Thanks,

64544/SNCI-2. I'd get the 125-watt over the 50-watt to give you expansion room in the future, since the cost difference is not that great.

Thanks for the advice,
