Review: Accurate compared to my Lab standard - Self contained with rechargeable battery. Easy to read screen and very accurate SWR and power measurement. Perfect for mobile or field use. Screen easy to read even in sunlight areas and with the backlight in dark. Makes adjusting your antenna easy and quick. Great value and comes with adaptors for Hand helds and mobile radios
Review: Seems to work; would be better with the ground plane and dummy load. - The main two reasons for having this is to test radio power output and antenna SWR. 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.

## Questions & Answers

**Q: No matter what changes i make the swr reading is always 19.99. what is causing this, and how do i fix it?**
A: Your antenna is bad

**Q: Will this mode work with Bao-Feng bf-f8hp?**
A: This unit is a very good unit works well I would buy it again yes

**Q: Is this the new version with the grounding connector on the output side?**
A: I bought this item a year age and it did indeed have the GND lug. 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.
