Thanks. I read the manual, looking past all the hype in it, and read
some reviews. It seems like a decent antenna that I could put up. It
has 2 elements per band on an 18' boom though, compared to 3/4
elements per band on a 24' boom with a TH6. I think a TH6 would
perform noticeably better, and might be more durable as well if the
hardware has been replaced with SS parts as was done on mine.

A Force 12 C3 is a very small but good tribander. I do not see any
reason
that it would not fit on your tower. I have one that I brought to KP2
just
for a contest weekend.

Thanks Dennis.
Those SWR readings are very useful. I just wonder how to go about
adjusting the driven element if it's needed. I have zero experience
with this. Would I first adjust the innermost section for 10M, then
the middle for 15M and then the outermost for 20M? And I suppose it's
best to try and get resonance on each band near what's shown in the
manual for your chosen band segment, which the other elements were
already set for, correct?
I haven't decided yet on which balun I'll use but I'll definitely
consider what you said about the BN-4000.
A lot of people recommended using a more modern antenna., but I don't
have a lot of options on what antenna to put or how to put it up.
Space is very limited here. You can get an idea of how limited from
the photo on my QRZ page. When I put up my tower a year ago, I was
also shopping around for a good antenna, but it had to be practical
for the space I have to work with. I found a lot of antennas with no
reviews and/or questionable specs, and the better, well known
antennas
were all too large. I was familiar with the TH6 but couldn't find one
at the time. The size of a TH6 is just below the limits of what I can
have up on the tower, but there's not even enough room to fully
assemble one on the ground while keeping it completely on my own
property. Even if there was, it would be very difficult/expensive to
maneuver for getting it up the tower. Building and raising 2 12-foot
sections is doable though. My contractor uses a very large bucket
truck that can hold each section lying flat on top of the bucket.
With
a strong support like that plus 2 guys in the bucket, it shouldn't be
too hard to put up one section, then bring up the 2nd one and guide
it
into the boom to mast clamp. If anyone knows of a better, modern
tribander of comparable size that can be put up in a similar way, I'd
like to know what it is.
