A bigger problem is a transponder that can only be connected to one antenna. There is an article in the December 2019 issue of Kitplanes Magazine about the proposed Canadian requirements and transponders. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=492975#492975 ________________________________ Message 3 _____________________________________ Time: 10:10:05 AM PST US From: Todd Bartrim Subject: Re: AeroElectric-List: ADS-B Diversity Antenna for Canada Hi Terry; You may already be aware of this but uAvionics is developing a Canadian version of their wingtip mounted SkyBeacon. More info can be found here https://uavionix.com/testing-sbx/ It will be called SkyBeacon-X. This is the option I'm waiting for.

The voltage regulator comes with an incandescent low voltage light and they recommend keeping it. For aesthetic reason in my new panel (part of the project), I would like to use an LED to match the other indicators. I believe they want an incandescent because the VR puts out a trickle current that will keep the LED slightly lit. Anyone know if that's true and if there's a workaround? Or is there a more serious functional reason it needs to stay incandescent? --Rick ________________________________ Message 6 _____________________________________ Time: 03:51:12 PM PST US Subject: AeroElectric-List: Re: Speaking of LEDs From: "user9253" A resistor is parallel with the LED will prevent the dim LED glow when it should be off. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=492987#492987 ________________________________ Message 7 _____________________________________ Time: 05:37:32 PM PST US From: Jan de Jong Subject: AeroElectric-List: Re: ADS-B Diversity Antenna for Canada Could a plastic airplane do with a single dipole antenna in the tail?
