Review: Simple, 5 Watt, 33 mile range test was absolutely Perfect! 465/567 SWR was 1.00 to 1.02 - Super easy to put together. I have a personal repeater 33 miles away, 2,180' elevation and was getting S-7 a great signal from a Diamond X-30A Vertical. Now with this Yagi I am getting a S-9+60 FULL Quieting.. Cannot get any higher/clearer. AMAZING. The SWR was 1.00 and 1.02 at 465/467 GMRS and I simply put the ADJUSTING slider to the far end. 33% Better than the vertical - Keeping in mind that any Yagi will FOCUS (propagate). 50-60 degree's in one direction rather than Vertical's 360. The Below Video; Was a 5 Watt - 33 mile range test. without effort. You can hear my 2,180' elevation personal (TREE) repeater-repeat my voice back, and I'm inside my home. this antenna is simple/effective & cost effective.
Review: Listen in on UHF satellite signals - I purchased the UHF 400-470Mhz single band version. I am working towards getting my technicians license and have been listening to local repeaters with a Baofeng and a Nagoya NA-771 antenna. Then I found out how to listen to a repeater on the ISS. With the Nagoya I could get a signal for 2 of the 10 minutes when the ISS was directly over head. With the directional UHF Yagi Im able to get a signal for most of the 10 minutes on a low pass that hugs the horizon. Just wave it around in the general section of the sky you expect the satellite, with the desired frequency (may want to adjust accordingly for doppler during the pass) and I got an incredibly good signal. I paired it with a 3foot UHF male to BNC male piece of coax, a BNC female to SMA female adapter for the Baofeng for quick disconnects and some bicycle handle bar tape. Pretty slick little piece of kit for so cheap! Not perfect though; it’s priced low because it’s made cheaply. It’s all aluminum tubing and once assembled is sturdy enough, but the metal is too thin to repeatedly unscrew, breakdown, then reassemble. It wouldn’t last too many cycles of that. Also be careful witg the set screws on the slide block when tuning the antenna, I stripped one of them.

## 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.
