I'm very well aware of rf polarization and the theory & practice of how it works. Patch antennas are a different beast which receive well merely by moving a few inches one way or the other, and good for vhf all the way to 800mhz. This is only a 12x14" flat patch antenna so placement can be anywhere. :wink: 73, n9zasOne problem, the TV antenna is horizontal and most all Land Mobile are vertically polarized. So you should turn the antenna 90 degrees to vertical polarization. See how that works.
