Purchased this unit as a replacement for a well used FMJ base antenna. Initial results have been more than satisfactory.
I just installed this Antenna today and WOW, I live in a community where I can’t have to much stuff outside and you can’t even see this antenna the element is perfect… I was using a different antenna before and my SWR was high, with this antenna I get what it shows on the comments. No external tuner and no issues, I love it…. Thanks for your help guys..
Works right out of box. Worked 6 stations right away.
