The best choice depends on your intended use for the instrument. Do you really
need a vector network analyzer? Much as I love lab-quality instruments, I don't
design antennas, filters, matching networks, etc., and while it would be fun to
measure some of those things in my station, virtually all of my use is checking
resonant frequencies, bandwidth, SWR, impedance and the length/integrity of
feedlines. All that can be done with a good antenna analyzer and you don't have
to spend a ton. That said, some models are more immune to strong BC
interference, if that's an issue for you (not for me.)
I'm quite pleased with my Sark 110. It's accurate and has all the features I'll
ever need. I particularly like that it goes up to 2m, unlike a lot of HF
analyzers. It's terrific for taking measurements on the tower -- can't beat the
size. Some may criticize the small size, but I haven't found it to be an issue.
No problem seeing everything with my old eyes, and there are some display modes
that show numbers like SWR larger. Pushing buttons with large fingers isn't an
issue. I sometimes wish for a larger, more rugged input port connector, but so
far it really hasn't been a problem. I have a little box full of adapters and
jumpers that I take with me up the tower. I guess I'd say for field use the
Sark-110 can't be beat, and I've found it useful in the shack, too (and it has
a USB interface with PC software, too.)

Good Day,
I am interesting in a graphical antenna analyzer and considering the Rig Expert
AA-30/54 or MFJ-226. If anyone has any experience with these, I would
appreciate any comments. Thanks & 73,Garry - K4OR
