Vortex Antenna Systems 1 to 1 Ratio QRO Commercial Choke Balun

£0.00

Here’s a novelty for any ‘Balun’ enthusiast. Vortex built the below balun back in 2016 for a commercial customer.
Saying that, it’s not really a balun as such but a 1:1 RF Choke (or ‘Choke Balun’ as they are sometimes called.)
The spec was that it should be capable of extreme continuous high RF power from 13 to 225MHz.

See info below for mechanical and electrical details
