This amplifier has been tested from 144-165MHz. 10W input will provide 160W output. The label on the back says 50W input but I really wouldn't drive it with more than 25W. You will need 12V at approximately 30Amps for proper operation. This is designed for repeater service and does not have a T/R relay for receiving.Drop me a note if you have any questions or concerns.
