hi cosmoc,
i have placed the aerial on the roof gutter of my house through the window, where the computer is, the cord wasnt long enough to get through the attic, anyways now my range has improved to about 50NM however i may eventually have it permantely on my tv aerial, while i am at it i may also extend my scanner, by installing a base antenna for the scanner as well, i was looking at the Diamond R777, if i place these antennas on the same pole on the top of my house with the tv aerial will there be any interference?
