That is probably unnecessary, just need to identify the actual fault so it can (usually) be fixed. It's probably not the antenna's main components, anyway.

You would have to make it from the component parts (balun, clips, soldering, etc), it's a one-off example.

I am wondering if the connection between the UHF and VHF elements on the antenna is the issue - see pic.

Yes, it could be the issue if either of the wires from the UHF section touch any metal parts of the antenna on their way to the CB-8269.

OK. So if I test with the clips and one part of the antenna is bad, then I guess I need a new antenna?

Maybe not, if you can fix it. Also, your antenna could be OK and the UHF signals might be bad.

I used to recommend the Channel Master 94444, but they redesigned it but kept the same model number.

The WINEGARD TV-2900 gets good reviews.
Add two alligator clips that have screws.

The WG TV2900 is now the same inexpensive, light-duty product as you now find on the RCA stick antennas. One can buy the same thing in an RCA-branded package for $4 in most (but not all) Lowe's home centers. https://www.lowes.com/pd/RCA-Outdoor...former/3724168

Still trying...
"Yes, it could be the issue if either of the wires from the UHF section touch any metal parts of the antenna on their way to the CB-8269."
The phase lines do not touch any part of the antenna.
"Maybe not, if you can fix it. Also, your antenna could be OK and the UHF signals might be bad."
Mebbe

Tree
I have a large pin oak in front of my antenna that has gotten even bigger since a tree in front of it fell a few years ago. This is most certainly what is causing my signal loss.
Would a different antenna with a wider beam-width help me?
or do I need to find another spot for my antenna...
I may try it in the attic, as I've noticed lower on the mast was getting better signal.

Thanks for the photo.
If the tree is between the antenna and the transmitting tower, that would certainly block the signals.

Lower can sometimes allow the signals to pass below the branches, but going from outside to inside the attic would make the signals weaker.
Something doesn't look right in the photo. Maybe I'm getting the mast confused with the boom, or maybe it is just the angle that was used for the camera location, but the antenna looks like it wasn't assembled correctly. Can you show us another photo of the antenna taken at a different angle, maybe more from the side?
Your situation looks a lot like this:

trees
LOL! that's me on the roof every week looking at the tree!
The antenna is assembled correctly, I have been getting the signal for 6 years without dropouts.
Yes, the tree is between the tower and the antenna.
Here is another pic (may have to bite the bullet and turn it to philly

Crap Shoot
OTA reception is a crap shoot alright!
I have my 7698p pointed towards NYC (70 degrees) and I get VHF ~low~ channel 6 from the back/side (PHI) 219 degrees, but when I turn the antenna directly to PHI I do not get channel 6!! LOL!! maybe because the UHF element is pointed that way and not the VHF, shrug.
trying to figure it all out...

Out of curiosity, would these horizontal metal screw threads coming from my u-clamp on the mast have any affect on my ota reception?

The bracket on your 7698P is entirely different than that
on my 7694P. I cannot help but wonder if the slotted screw
is grounding out your system????
