This a totally deserved honor. I have learned so much from you and others on this list. I feel much more confidant starting the wiring of my Cub than I did 2 years ago. I also know that I can always ask questions in this forum, which is a real anxiety reducer.

Does it have multiple antennae inside and use bandpass filters to route signals to the correct antenna? I am trying to determine if I can share an antenna between my UAT ADS-B unit and my Mode S transponder. Thanks.

It is a wide band antenna that operates at both 978 and 1090 Mhz. Those frequencies are close enough together that most transponder antennas will work satisfactorily at either frequency. Someone please correct me if wrong. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=491635#491635 ________________________________ Message 4 _____________________________________ Time: 08:01:51 PM PST US Subject: AeroElectric-List: Re: Dual Band Antenna Question From: "markfw" Joe, That certainly is a possibility, but when you look at the web site info, the vendor lists this: Frequencies Covered 960-1220 MHz 1030-1020 MHz 978 MHz 1090 1 MHz To me this implies that there might be more going on than just a wideband antenna.
