Pre Amp is ok if you use band pass in front of the pre amp. The henry amp should give you good service. If it's a 100watt model run it at 80 watts.

I have a Henry UHF amp in hand. I would think any amp would work with simple RF out of the repeater. Am just curious more about sensitivity than anything.

You can get it a bit better with some time tuning. If your repeater is out of the box it will be def and will need to be tuned.

Receive would be 445-447mhz. Preamp necessary? What about driving an amp: any recommendation there? An amp putting out 60-80 watts. Thanks, Brian, k5in
