Default Dynon ADSB-IN Installation for RV12

As you guys are starting to see, I'm doing a lot of things to get my new to me RV12 working and equipped the way I want..

I'm ready to order the DYNON SKYVIEW ADS-B 472 IN box from Aircraft Spruce. I can order it with the standard 4 ft. harnss, or for a little more they will can provide a custom harness of different length..

Can you guys tell me if the 4ft harness should be long enough for my RV12? Sure, I suppose it depends on where I mount the box. Well the honest truth is I don't know where most people mount them. This is all so new to me.. So where have most of you guys mounted them, and how long of a harness do I need? I'm planning to buy one of the short rod antennas, rather than the more expensive blade antennas. The rod antenna should be fine for ADSB RX, correct?

Yeah, I know I could order the kit from Van's for a couple of hundred more, but to be honest I haven't much luck with ordering from Van's lately, but that's a different story for a different time...

Plans call for it to be mounted on the right hand aft side of the baggage compartment bulkhead. Opposite side from the fuel pumps. I have attached a PDF showing how it is supposed to be mounted. Also shows the location for the stick antenna.

Default Dynon ADS-B IN

I have a regular RV-12. The 472 is mounted above the com radio using brackets I bought from Vans. The antenna is behind the seat in the baggage compartment, on mine it's on the pilot side. A 4 foot cable will not be long enough. As I remember I bought the entire kit from Van's and it had the 472, the brackets, the antenna, and the coax.

But if Van's backorders are that bad, you can make your own brackets and buy the antenna and coax from another vendor. A guess is the coax would be 12 to 16 feet, but that is a just as guess.

IMHO mount the ADSB module as close to the antenna as practical, thereby reducing the length of the coaxial cable needed. The DB9/RS-232 connection length isn't as critical as the coaxial cable length. Besides, the DB9/RS-232 cable is very easy to custom make.

FWIW In my airplane (not an RV12) the module is mounted only 16" from the antenna so I get excellent ADSB reception anywhere I fly.

Joe -

Sometimes a photo is worth a thousand words. My older RV-12 has the ADSB-472 mounted above the radio using two brackets and a mounting plate (all Van's parts). Below are a couple of links to photos. Don't know which mounting location would be better ... but mine works great as is.

The rv12 mount location is not on the rear bulkhead, but the RV12IS is.
So looks like you have the regular RV12,which in turn mounts behind your panel behind the radio area.
Look at the plans online for your model, it shows it very well.
Buy the RV12 plans USB stick for $10 from Vans.
Good luck.

Seems you have an RV-12 -- not an RV-12iS. Below is the plan sheet (KAI Section 53) for the original -470 ADSB unit as installed in an RV-12. The -472 unit basically replaces the superseded -470 unit. Van's sells a custom mounting bracket for the -472 but it is simple enough to make one yourself.

If you have a GTR-200 radio, order the 472 from Van's, with everything you need.

It will mount right on top of the GTR-200 with the brackets provided.
