Antenna options for SV-ADSB-472

[blue172]

The SV-ADSB-472 receiver installed with my SkyView HDX is working great with the included monopole rod antenna. However it seems really fragile and susceptible to breakage. Would another transponder antenna like the Comant CI-105-6 work as an acceptable substitute to the monopole antenna for ADSB-IN?

Yes. See page 14-9 of the Installation Guide.

OK, Thanks. Didn't see this:

Antennas available include (but are not limited to):
...
Rami AV-74 (TSO’d)

The Spruce product page for the AV-74 says: "This antenna is a direct replacement for the CI-105".
Seems like a match but I would be happy to hear any real-world PIREPs on the matter.

This is what I'm running for both ADSB and transponder (two separate antennae) - it's physically the same rod and ball assembly, just encased in RF-transparent epoxy. Much stronger and more aerodynamic.

Same here. Works fine.

Believe ! You’re overthinking it.
The ‘rod’ type is made of a brittle alloy & they typically break (the broken shaft will spin) just inside the mount which is usually caused by a bump when washing or polishing the plane. I had stopped using them on installs around 20 years ago. The Comant version is too expensive IMO - YMMV

I see a lot of $40 TED antennas out there in the sub-250kt GA fleet posing as the $140 CL101. They seem to do ok. Maybe get flying with the one Van's sells. Then if it does break down the road, replace it with the fancy 300kt blade antenna. Just my 2 cents.

I have three DM N150-2-2 blade antennas you can use. Two came off Citation jets and one off a King Air 200. I can sell them for $50 each plus shipping.

I ended up with the Comant CI-105-6 and it seems to be working just the same as before with the monopole.

You can receive ADSB on a wet piece of spaghetti, so it’s pointless spending loads of money on fancy antennas unless, of course, you want one for aesthetic or robustness reasons.

Items similar to the Comant antenna are certainly stronger and less likely to get damaged than a TED aerial but don’t expect any performance change.

The ones I have at my house I made myself from lengths of TV coax and have detection ranges of around 280-300 miles but I don’t think a 1.5m antenna sticking out of the bottom of the aircraft would be too practical

Same here. I've got some cheap rabbit ears on my home ADS-B receiver, which works fine. Seems like you don't even have to be all that close to a wavelength fraction.
