other two frequencies of operation. There is room. The reason for
this silly situation to begin with is just the misconception held by
our ARES people that the internal tuner of the FT900 could handle the
mismatch.

Ed, I worked up some numbers for you at 3.98MHz, and the numbers
demonstrated that the main cause of system inefficiency was coax loss (and
not the ATU).

If you are focussed on VSWR and bandwidth as you seem, you need a radiating
dummy load. They have certain merit in this application. Google for "TTFD
antenna" for an example.
