Hi Ian,

Thanks for your comments.

My hope was to use a v beam instead of a rhombic.

The V is relatively easy to steer, especially if the performance
doesn't change much if either leg is moved. Note that I hope to leave
one leg of the beam fixed and steer the az by varying the position
(and the V angle) of the other leg. Not sure how much changing the
angle of the V impacts the performance, which is why I asked for
someone with modeling software.

My hope was to exploit the high gain, simple construction (but poor
receive) of the V for transmit only and to use the modest sized FO
yagi for receive only.

If I can get 19 or 20 db from a big V beam, I can probably tollerate
the limited operating time as well, Q's with big guns should take only
minutes and medium sized stations should be workable in a 20 minute
window.

If the computer model predicts a usable gain, I'd like to try putting
one up.

Regards,

Art
