[TowerTalk] Mosley Antenna Question

[Cox, Norman R.]

   I can't exactly remember, but I think the main difference in RG-213 and RG-8 is that one has definite MIL standards and the other (RG-8 I think) had more-or-less standards, but varied by manufacturer.  I imagine that, at the time the antennas were introduced, 213 and 8 were the two most used by amateurs, the antennas were evaluated with those, and so that's what they recommended.   I would suspect that newer, low-loss cables would work ok, but you might find the characteristics changed slightly (due to the lower loss).

Subject: [TowerTalk] Mosley Antenna Question

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
