[Bullwinkle]

using a db4 my "window " is about 5 - 10 degrees .... tough to get 4.1 and 10.1 in the same alignment but can be done - a good blow will shift things if not ratcheted down

edit: details

"HIGH GAIN ANTENNA: High gain antennas have narrow beams and may require a rotor to move the beam (rotate antenna) between stations with a wide angle separation. "
