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.
