I would like to obtain information from anyone who has used the Force12 Mag2/2
subject yagi. I have had one still unopened in its shipping carton for a
couple of years and am trying to decide if it would be worth installing. I
have the Steppir Monstr at 72' for 3 elements on 40. I originally purchased
the Force12 before the Monstir was available and because it seemed for a little
more money and installation complication, 80m would be available. (Actually it
was a lot more money and will be a lot more complicated installation.)
The Force12 uses both relay switched coils (for moving resonant frequency in
the band) and linear loading for the 80m on both elements. Using Eznec I have
not been able to get gain when the linear loaded is placed at the center of the
elements but I can get about 3.5 db gain when the loading is moved to the end
of the elements similar to the Steppir 40m dipole addition. (I didn't model the
coils). Force12 specifies about 4 db gain with their center loading
installation. It may be that my model is inaccurate. The height that I have
modeled is 72' which is the height that I would install it on a LM470 crankup.
So far I have only heard from on other "user" of the Mag2/2. He bought it used
and decided not to install it! I will appreciate comments.
