[TowerTalk] [tdxs-list] Beverage Antenna Problem

[Mike Bragassa]

I would start with substituting the 9:1 balun for a known good one. Also try substituting out the terminating resistors. Lightning could have got the resistors?

I would also try your analyzer on the feedline using a dummyload at the opposite end OF THE COAX. Check for an open or short in the coax.

If the wires are visibly OK, it can only be one of those three things.

  I have been trying to repair my 4 beverage antennas.  Wires and terminations are good.  2 of the beverages work well, 2 are "dead"  I have checked the coax and connectors are ok.  Other than broken wires, what can go wrong with the transformer?  What the heck am I missing?  Short to the core?  I will try moving a transformer from a working Beverage to a dead one to see if that is the problem.  Both "dead" ones have RG-59 coax with foil and shield to them.  The working ones have other types of coax. All have transformers from ON4UN that used to work great.  3 are 600' one is 800'  the 800' and one 600' are not working.

  I guess I should try the substitution of another transformer first...

  Thanks
