The Lake Area Radio Klub used a pair of Arrow dual band Yagis a few years back and it worked very well. We simply followed the harness arrangement described in Martin Davidoff’s (k2ubc) “The Satellite Experimenter’s Handbook”.
I would strongly recommend a copy of the book as it is full of great information!
I have two Dual-Band 2 Meter/440 Yagi's that I would like to use on a Rotator, with one in the vertical polarity and one in horizontal.
Is there a phasing circuit or system that someone can recomend to allow both of these antennas to coexist on one coax input to my radio?
