[ACARS] Multiple Scanners

My way of 'combining' two recievers from one antenna, is a three =
resister 'triangle', using three 100ohm resisters connected end to end =
and a SO239 socket at each of the three joints, this gives a 50ohm =
appearance to all three connectors.
 Thus, antenna to one point and the two recievers to the other two =
points, each connector will 'see' 50 ohms.
 In practicle tests, very little loss can be heard, and with such strong =
signals from the ACARS system, any losses can easily be compensated for =
by turning up the AF gain.
 Hope this has helped.
