Lets reach out to older hams in Nursing Homes N0HWJ on 3/3/21
There is a ham operator that had a 'medical Issue' and has been confined to a nursing home to recover. One of the members of our club took the initiative to set him up on a DMR radio and it made a world of difference in his recovery, not to mention the increase in his strength by keying the mic. Names withheld to protect their privacy.

Been working well using an auto tuner, my latest issue was a squirrel that for some reason liked to chew through the cord holding up one end. We had a discussion and my flying pliers won. no more problems with that rodent!!

Ok, so it occurred to me that I did not measure the length of the ladder line, and it was much longer than I thought. I cut it back to the recommended length, straightened it out and antenna is now working as it should. Measure twice, cut once... Thanks!!!

Ok so I am working on building this antenna, got both wires at the correct length, added the ladder line and coax, the tuning is off the scale. It may be possible the ladder line is too long, it had tape on it saying it was 39 ft long but that may not be right. Seems a lot longer than that. also I have a looped up section as it seems too long, does that affect my swr readings?

I can only get it roughly 25-30 ft off the ground due to location problems. Could this be causing issues too? Trying to learn as I go...

No replies so here is what I figured out.
The guys at Alpha antennas are in Puerto Rico working with earthquake recovery efforts.
The 'coupling' at the base of the aluminum mast is actually made of brass. I drilled it and used a Heli-coil that I shortened to fit, seems to be working just fine now.
