To test radio output, you really should be using a dummy load. It's the only way you can get consistent and comparable results. Dummy load sold separately. To test SWR, getting an accurate reading that is consistent and comparable requires a ground plane. This used to be included a few years ago, but not anymore. Unfortunate. You can make one if you are so inclined and capable. I am not. Anyway, this unit will give you good ballpark figures. Review: Great watt meter! - This is an absolutely amazing wattmeter. I use it to test UHF Repeaters in the office and in the field. Very reliable, simple, easy to charge, accurate. ## Features - SW-102 is not for DMR radio , only Analog . - low insertion loss (0.3 decibels or less) structure allows it to be permanently connected. - Build in Frequency counter. - VSWR.

Hope this helps. **Q: Is it a proper way to measure swr on ht radios? just put this unit in between ht and antenna ? i was told it breaks the ground and gives wrong results** A: I believe it does interfere with the ground plane. I have noticed that the positioning of my body, arms and hands as it relates to the positioning of the radio affects the SWR reading. So I'm not sure that you can rely how on the accuracy of the readings. Maybe if you have a base antenna setup at a distance from the radio, then you may have reliable SWR readings. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Seems to work; would be better with the ground plane and dummy load. *by E***Y on August 26, 2024* The main two reasons for having this is to test radio power output and antenna SWR.
