Review on 📻 BTECH AMP-U25 UHF Amplifier: 20-40W Output, Analog/Digital Modes – Compatible with BTECH, BaoFeng, Kenwood, Yaesu, ICOM, Motorola Radios by Fred Vazquez

I have used this amp with three different 4-5W HTs. In a car with a new battery and a voltage of 13.5+ VDC, the maximum output power of the amplifier was 10 watts with an SWR of 1.3:1. Reducing the HT power to 2W results in a maximum power output of the amp of 4-5W. It is essentially twice the power and not worth the price in my opinion. I would not buy it again nor would I recommend it to anyone. Update: I've had this amp for a few months now and have used it with at least four different radios and it remains pretty much useless. I can open more repeaters with a 19" plug on a portable device in the car than with a connected amplifier. The power meter shows a maximum output power of 8W with an input power of 4W. Big, big waste of money.
