amplification often solves it.  The preamp on the 1026 btw is NOT useful
for this purpose as it's hard wired to the internal whip on that model."

The MFJ noise cancellers require the the signals from both antennas  are
equal level.  That means that with the 1025 that the "noise" antenna
needs a preamp because it is usually a smaller, non-resonant antenna. 
There are "gain" controls on both antenna inputs that allow you to
precisely adjust it so that the signals are equal on both inputs.

The 1026 has a built-in preamp for the "noise" antenna input that *is*
able to be used with the built-in whip antenna *or* an extenal 
"auxiliary" antenna.

I recommend the 1026.  The extra $10 or so that it costs is insignificant
and well worth it for the built-in preamp.
