The antenna works incredibly. A lot of stations in Norway were wondering what I was using and if I was using a 1 KW amplifier.

A SMALL and GREAT antenna. I wanted something small and easy to carry to my activities on the mountain, weighs nothing. Perfect fit in RX / TX. A great design and success for the activators of SOTA.

Hi, personally I am delighted with the antenna. It is working great and comparing with the Diamond X-200 that it had, it has more reception and in TX it is noticed a pair of signals more.

After trying many verticals, today I work with what for me is the best vertical for 11 meters. The performance far exceeds 5/8. Best of all, the absence of QRM.

Compared to an X-50 it has nothing to do

The SWR is perfect, the antenna is a gun and works better than my yagui with more elements.
