[amsat-bb] Best HT for satellite operation?

​Hi Greg!

I think the consensus was that Arrow users - or those with
similar crossed Yagis - needed to make a 90-degree twist
when going to transmit to AO-85, and then twist back after
your transmission. This was the case where Elk users, or
those with Yagis in the same plane, wouldn't have to make
a twist going from receive to transmit and back. For most
other satellites, this 90-degree twisting wasn't normally

As with any satellite, some twisting might be needed to
counteract fading, regardless of the antenna(s) being
used by the operator. This is a separate thing from the
advice specific to AO-85, and the other upcoming Fox-1
