This is not a booster or amplifier. This is a duplexer and really not a good one at that. It is used for a repeater that has both inputs for receive and transmit allowing for use with a single antenna. I would recommend a repeater with less than 50 watts output. The duplexer comes pre-tuned for the GMRS frequencies with 462.mhz as the transmit frequency and 467mhz for the receive. Please note: I would not use the duplexer in a facility that has a lot of other repeaters. The duplexer is a notch type duplexer and in area that has more repeaters, it’s best to have a pass/notch as it’s better for better rejection of unwanted frequencies.

Q: You can configure it with these frequencies: low 462,725 / high 467,725.

Thanks for your concern on this item. The item in Amazon warehouse was already set the frequency to 462MHz and 467MHz, and Amazon can not set it to other frequency and send to you. But we can tune and ship this product from China to meet your requirement 462.725/467.725. Would you accept this solution?

Q: What is the process for ordering the 50w duplexer tuned by you for low 462.575 / hi 467.575 ?

Ordered the duplexer; it showed up in two days and in good condition (as opposed from ordering direct from China and taking 6 months (like the one it was replacing). Connected it up to a spectrum analyzer with a tracking generator, set the frequencies I wanted, and tuned the cavities by turning the tuning rods until I got the dip where I needed it. Changed the cables around to the other cavity set, and retuned for the other frequency. Made sure everything was locked down, and done. If you don't have a spectrum analyzer, you can do the same with a VNA.

Q: I'm setting up a gmrs repeater on one of the gmrs frequencies. is it required to tune on exact frequency?

Yes, need to tune it to exact low/hig frequencies to meet you requirement.The item in Amazon warehouse was already set the frequency to 462MHz and 467MHz, and Amazon can not set it to other frequency. But we can tune and ship this product from China to meet your requirement. We need two business days to tune it. To speedup the delivery, we will ship it by DHL and delivery time is just around one week usually but the price is 30USD more than the default frequency unit in Amazon warehouse.
