## Customer Reviews

### ⭐⭐⭐⭐⭐ Base had to be reworked.
*by L***D on June 11, 2025*

Haven't deployed it yet, but from the testing I have done with it, it works quite well.

### ⭐⭐⭐⭐⭐ Very adjustable, works well on GMRS
*by L***G on March 31, 2022*

My only knock against the antenna is that the supplied allen wrench isn't the correct size and could strip the adjustment screws if not careful. Fortunately, I noticed before loosening the screws. It appears that included allen wrench is standard and the screws are metric? Either way, double check before you go to loosen them.As for build quality, it seems pretty robust. This is going in an attic, but it looks like it would probably hold up outdoors for quite a while as well (nothing lasts forever of course). It only took a couple of minutes to get it adjusted. The markings are nice and readable. I initially tried setting the top and bottom element to midway between 460 and 470MHz markings and I got 1.01SWR for the lower 462Mhz channels, the upper 462 channels jumped to around 1.2-1.3SWR and the 467MHz repeater channels were up around 1.6-1.9SWR. I adjusted the lower element to 470 and kept the upper element at 465 and the lower 462 channels were all at or around 1.01 and 467 improved to about 1.5. I adjusted the top element to 470 also and then all of the channels in GMRS are now around 1.01-1.04SWR. I don't have a full spectrum analyzer, so I can't see what the lower frequency response is, but it anecdotally seems good just based on Rx behavior, up in the 160s, but I get very good reception on the closest weather radio channel (and it still isn't that close). Better than I can get on my Nogoya UT-72 sitting on top of my car. I haven't checked, nor can I, the 145 range for VHF coms.But I suspect this is a fairly narrow band antenna, even if reception is good for Wx band. But great for GMRS!

### ⭐⭐⭐ They are very close to getting it right
*by P***T on December 6, 2022*

HYS is very close to getting this right, but they are not there yet. I had to re thread (tap) the 10-32 holes for the radials. Surprised it was an English thread, but that's okay. Then on first bench testing realized the two snap rivets that hold the vertical structure to the brass base were very loose with gave intermittent contact. Gently tightened in a vise with wood on one side, and contact improved, but there was still some movement. Finally added a small screw driven steel hose clamp at the base, and that did the trick. I think in the wind on the tower, even after pressing the rivets a bit, they would just come loose again. The adjustable sections are great! This design is very close, just needs some more improvement. BTW, I have their 3 element 400 MHz yagi, and that product is great!
