Easy to put together and tune for 10m. Mine is only up 25 feet (tripod mounted on the ground weighted down with cinder blocks and guying) but works remarkably well from upstate (FN13) New York. Have over 40 states and 30 countries since I got the antenna in miserable band conditions. I use it for FT8, CW and SSB, with a max of 200w. I am happy with this antenna.
This is the highest quality 3 element beam antenna I have ever purchased in my life, BAR-NONE ! The boom and all the elements fit together perfectly. When I connected my antenna analyzer it tuned up perfectly the 1st time. There's not anything I don't like about it.
