I have to admit I purchased this mostly based on price, although the specs are comparable to the competition. I hoped it would be a good value for the money, and I was not disappointed.

The component parts arrived neatly arranged in plastic bags specific to the part being assembled. Assembly was simple. I spent about 45 minutes putting it together. The engineering and component quality are quite good. For example, the plastic sleeve that holds together the extension tubes on the reflector, driven element and director are designed to hold the screws pointing down....out of the rain. Some of the parts are cast aluminum for strength. I liked the caps on the ends of the elements, which will reduce wind noise.

The gamma match is easily assembled, and not fussy to set up. I use the lower part of the band for CW, SSB, and digital modes, so no cutting of extension tubes was required. For users operating on the upper parts of the band, six tubes will have to be cut to length as shown in an accompanying table. A hack saw would make short work of that job.

The antenna is about 9 lbs (4kg), with a wind surface of a little under 1 square foot (0.09 sq meters). I was able to use a relatively inexpensive TV antenna rotator to turn it.

I tested front-to-back and front-to-side performance with a fellow ham today. While we didn't test the specs exactingly, performance was clearly about as expected. The other test was usage. Since putting it into service a week or so ago, I have worked local stations, a dozen stations at 600ish miles on a sporadic-e opening using FT8 and other stations on meteor scatter on MSK144.

I'm quite pleased with the antenna, and expect years of good service from it.

Put together fairly easily, all parts there and instructions straight forward. Tuned up at 50.6 with no cutting. I'm sure it will perform remarkably (when the band opens one of these decades) Its light but strong, I anticipate it lasting many years

The build quality is very good and the assembly instructions were easy to follow. The instructions use metric measurements but no problem using a metric rule to ensure all dimensions are correct. Assembled the Yagi with strict adherence to the gamma match recommendations. To test the Yagi, it was set-up on a 10 ft. section of EMT on a tripod. SWR was best at 50.500, which is where I want it. The gamma match makes it very easy to adjust SWR as needed.

It is very simple to assemble, and a TV rotor will work fin to rotate it.
Nor for use with any legal limit amplifier,

this antenna is compact and has excellent swr where ever you tune on the band.
