Mike,

I have a TA-53M @ 43 feet on a small 2nd tower. I used a ferrite bead choke and RG-8X...about 60 feet. Of course I don't know what the pattern looks like, but the SWR curves come close to matching what the manual states.

Additionally I have a PRO-67B @ 68 feet fed through a Balun Designs 1:1 and DX Engineering 400 Max coax. Again no issues here either.

The usual disclaimer...Your Results May Vary...

Doug - K1ZO

Over the years I have heard stories of unexplained failures with Mosley antennas which were equally unexplained as having to do with the selection of certain coax cables. One recent incident was with a local here that had trouble getting a PRO 67 to ‘cooperate’ only with the use of RG 213 cable. Recalling this story, I have been asked to assist with the install of a Mosley TA-53, 5 band beam on a 14ft boom. NOTHING in the manual (which is dated) suggests this but an on-line review of the TA-63 and a peek at a manual found on-line also seem to suggest that the ‘recommended coax is RG213”. Any comments on the validity and reason for the use of JUST RG-213 and not some other 50/52 ohm cable? Thanks.... - Mike
