[amsat-bb] M2 70cm Cross Yagis on LHCP

[Burns Fisher]

A friend of mine discovered that M2 actually has polarity reversers for
their CP 2m and 70cm antennas.  They are several hundred USD, but you might
look at the manual to get a hint at how they do it.  I'm guessing it might
be reversing which elements have the delay line, in fact it's probably a
different delay line since the horizontal and vertical elements are a bit
offset from each other.  Hope this helps.
