Hi,
Give the SteppIR guys a call, their number can be found at
www.steppir.com
They are working on two versions of a transmit-receive 40-6 meter
antenna.
The full-size 40 meter 3/4 element version is the one that George W5VU
saw advertised in this month's QST.
They are also working on a MOXON version that will have shorter
elements (and probably reduced boom length) due to the design of the
elements on a MOXON antenna. I'm sure the details will be release when
the engineering and testing are complete and they are ready to start
taking orders.
Mike, K7IR posted this information on the SteppIR reflector a few days
ago so I believe the information to be correct.
They are very responsive to phone calls and I have no monetary
interest in the company, just a very satisfied customer....
73,
George / KF9YR

The MonstIR is an amateur version of a receive only antenna that
is sold to agency buyers (the commercial version includes coverage
to 3 MHz with switched coils). Based on the specs and pictures,
the elements are in the same position as the current 4 element 20-6
meter antenna.
Doing some quick modeling with YO, the MonstIR will be capable
of about 7.0 dBi free space gain/20 dB F/R on 40 meters and
about 7.3 dBi gain/18b dB F/R on 30 meters. The gains and F/R
are better than any of the short/loaded 40 meter antennas but
are not quite as good as a "full size" (ca. 46-48' boom) three
element 40 or 30 meter yagi.
Still, for a single antenna with coverage from 7 to 30 and 50-54
MHz, it merits serious consideration.
73,
... Joe, K4IK
