down-tilt is specified when ordering the unit other than the original paperwork, the only method would be to have it tested on a test range
and that would probably cost more than ordering a new one............

I'd like to ask how one can determine the electrical downtilt of an antenna? I just put into service a RSF/Celwave Super StationmasterR Model 10017-6 that is designed for 925-960 MHz on my 927.5250 repeater. The added gain factor of the antenna (an additional 4dBd over what was previously in place - a Decibel DB586-Y) does not seem to benefit the receive (at 902 MHz). I gained what seems like a little extra receive range, but not equal to what I seem to have gained in transmit coverage. This discussion thread leads me to wonder if maybe some electrical downtilt may be affecting the receive frequency? Is this possible? Antennas are not my strong point. ;-) Thanks, Mark - N9WYS
