Review: Amazing RF Amplifier... - Wasn't sure this was going to meet my expectations, but have to say that I am extremely happy with this purchase,I went with the dual analog/digital vhf unit,to boost the transmit power of my many ht's to better reach 2 repeaters in my area,one being approx.13miles away,the other about 17mi. I am currently using a Radtel 600,5 watt output radio in the 147Mhz range,and have gotten very impressive output levels from this BTECH amplifier,It bumped my power output to between 55 and 60 watts,and my swr is right around 1.45-1.49,I hope to reduce that with a little work but is well within an exceptable level for now,my signal reports have been good and no complaints on my transmissions,as before I used this amplifier my transmissions were weak and hard to hear at times,much clearer now! I am using a Nagoya UT-72 loading antenna,and a low loss 240 coax from HT to amplifier.I feel that this was a great option for me to turn my HT's into a 50-60watt base station.The unit is well costructed,small in size and very easy to hook up,as for longevity I will have to wait and see,but as or if any issues arise I will post updates, but as of this writing I am very happy and would not hesitate to recommend this amplifier to anyone wanting to boost the output power of their handheld 5w radio. Just be sure you select the right model for your needs,VHF or UHF model,and whether or not you want analog only or analog/digital unit. 73
Review: Nice little amplifier - The BTECH AMP-V25 amplifier is working exceptionally well. It's just what I needed for those times that call for a little "umph".

*by G***0 on March 10, 2026*

The BTECH AMP-V25 amplifier is working exceptionally well. It's just what I needed for those times that call for a little "umph".

### ⭐⭐⭐⭐ Good Quality, puts out fat wattage, low speaker volume
*by B***N on December 31, 2019*

Bought this to work with my Baofeng F8HP 8w handheld. As the input for the radio only specifies 2-6w, I have done testing with both 1w input and 8w input (the only two modes that radio supports) and it works flawlessly with both. I am not sure if it puts out different amounts of wattage though, as I do not have a meter to test with. Setup is very easy - the included hand mic sounds awesome with it. The setup I used was the reverse SMA to SMA adapter in my radio, the the SMA cable to the input on the amp. Then I ran the control cable to the radio from the amp, and plugged the hand mic into the amp and used that for PTT. It sounds great! The only 2 downsides to this unit are the amount of extra cabling you need if you want to use the external mic (which I'm not knocking it, that is the primary design, it just becomes cumbersome next to a standard mobile), and the fact that the speaker is bottom firing, which in my car makes it very quiet. There is no line out to hook up into a seperate speaker. If there was, I believe this product is worth every bit of 5 stars.
