iPro-Antenna Baluns

iPro-antenna baluns, we have NOS of these units available as we made the replacement “Black Box” unit as described on the webpage http://www.proantennas.co.uk/iprohome.htm

Designed & built by Geoff Brown (ex G Whip antenna products owner) these are a mega step up on the original white box balun that tended to fill up with water. This last batch were made in 2017 when we received the new “K” cores and is a further improvement yet again as return loss (terminated VSWR) has been made even better, so another mega improvement. Simple to fit and complete with nuts/washers.

We made hundreds of these fully resin potted units for iPro-antennas and we have a few that are now surplus to requirements.
