## Description

Review: Missing instructions and hardware - I can’t fault the seller for this. In fact I got the antenna days earlier than expected. Siri, on the other hand disappointed me big time… NO instruction manual of any kind were included. I had to go online and search for the manual as to trim the antenna for 10 Meter SSB. Hardware was also missing. Not enough PK screws for the elements, and hardly any 6mm grub screws for mounting to the boom… Luckily my online manual stated the size of said missing screws, and I purchased them at the local hardware store.. Antenna is simple to assemble, and VSWR is good after cutting.
Review: Perfect lightweight antenna - Package arrived earlier than expected. Packaged very well! Set up was really easy. I had the antenna assembled and mounted within an hour. Adjusted the match using my Nano VNA and had a perfect mid range match. First contact was a POTA station 1705 miles away. Very happy with this antenna. I'm considering buying two more and making them a stacked array
