[TowerTalk] 40 Meter Beam problem

[Dave Thompson]

Thanks for all the replies.  My MFJ-259B does not have a TDR.  When putting up the beams 3 years ago I did have a problem with a bad double connector.  Replacing it cured the problem.  I plan on replacing the balun with the coax type balun.  This was on the beam for over 20 years with no problems. 

I used binoculars to look at the feed point of the beam with no problem found from the ground.

I plan on contacting a local tower guy next week.
