See http://www.hard-core-dx.com/nordicdx/antenna/special/mfj1026.html Jeff; it was a mod.

I thought the 1026 included the BC band, or was that a mod ?

Mike,

I based that on what W8JI states on his webpage, which says 1.8 to 20 MHz.

IIRC, Tom designed that for MFJ.  Maybe that was a typo (on either Tom's
site or in MFJ's manual). Or perhaps the performance drops off to some
degree above 20 MHz. I don't know.

Hi Mike,

I was trying to address the particulars of N2IC's situation which
involved the higher HF bands (although at this point in the sunspot
cycle, perhaps I should have included 20 meters).

Reading the manual I have for the MFJ-1026 says "The MFJ-1026 is
optimized over the range of 1.8 to 30 MHz". Does the MFJ-1025 only go to
20MHz?

73, Mike W4EF........

Mike, is there any reason why you tested it above 20 MHz? That's outside
the 1026's specified frequency range.
