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.
