Review: Yagi works good - Hard to mount lmr400 to the connector with mounting bracket wish it had another set of holes on the backside to mount pole it would have been easier but antenna is good . talking 62 miles to repeater in front and 38 miles to the side with a 20 watt Anytone 779 would buy again o it’s 47 feet in the air out talks a tram 1486.
Review: Just buy the Yagi, you needed one anyways. - Used this to hit a repeater 10 miles away from ground level indoors through a closed window at an upward angle. Works flawlessly with good signal reports. I can only imagine if it were outdoors at a higher level with an antenna rotator. It was very easy to put together and assemble. My goal was to use this as an indoor antenna only. One thing that I did notice is that if you were to put it outside you would definitely need to weather proof it some more. Use your imagination. Other than that I am super pleased with it. I have bought an assortment of gear from this company and have never ever been disappointed. Thank you so much!

## Questions & Answers

**Q: Want to use this antenna for my midland gmrs radio as a home base. how do i properly ground it ?**
A: no ground is needed. it grounds through your coax cable shield at transmitter

**Q: Good reception but for receive-only on 461 mhz i'm not clear from the instructions how far to slide the swr slide block before locking it?**
A: you need a swr meter to properly setup when you transmit. generally i have found all the way in is best swr. it is called a  Hairpin Matching stub.

**Q: Is this omnidirectional? If not, any ideas for GMRS?**
A: Yagi antennas are not omnidirectional. They are very directional. The elements are longer in the back and shorter in the front. Like an arrow head. Also the elements are oriented verticaly.
 For omnidirectional antennas use whats refered to as a vertical or ground plane antenna. They radiate in a circular patern. They come tuned to either ham or gmrs frequencies. For gmrs the frequency will be 460-470 Mhz. All antennas have a gain number that is listed in db.The higher the gain the more effective radiated power the radio will make. An antenna with 3db gain puts out a weaker signal than one with 6db gain.  In general for omnidirectional antennas a vertical with 6 db gain is a very good all around pick. And remember the antenna must be tuned for the gmrs band and not the ham band. 
 Coax cable is also a huge factor in getting a strong signal. In the gmrs band the rg8x cb radio coax will not work. 80 percent signal loss over 100 feet is guaranteed. For gmrs radio a good economical coax choice is LMR400 . It is higher priced than cb radio coax but the cb coax is totally a waste of money for uhf radio. 
 Hope you find it helpful and that you experiment and always improve your station and have fun.

### ⭐⭐⭐⭐⭐ Yagi works good
*by L***. on January 7, 2026*

### ⭐⭐⭐⭐ Great Yagi
*by T***E on April 17, 2025*

This is a great Yagi, power handling and frequency range are perfict for many ham radio projects such as links or base to repeater applications. The only week point that I see, is the small screws to hold the elements to the boom. If you have rivets available, I would use them insted of the small screws. Other than that, it's a great product for home use!
