Which wingtip for archer antenna?
Couple of questions;
Has anyone installed a GMU11 Magnetometer in the same wingtip as an Archer Nav Antenna? Is there an advantage to putting the Magnetometer in a wingtip at all? Are most people putting it on the same rack as the AHRS now that Van's sells a kit for that? Thanks! |
Which wingtip for archer antenna?
My avionics supplier recommended mounting the Garmin GMU 11 on the aft deck next to the rudder and horizontal stabilizer. Wiring run is probably shorter/easier than in the wingtip.

I tend to use the right but it mainly depends on ease of installation of the coax.

Walt-
The right wingtip would be easier for sure re. routing coax, but that would logically lead to putting the magnetometer on the left side, which seems inefficient re getting it on the can bus? Terrye- Any problems in that location? Seems like there's a lot of steel back there, especially since I'm building a taildragger. |
I like the wingtip location for the GMU11 on the taildragger and the rear deck for an A model.
The archer antenna is a couple of strips of aluminum so neglible/no effect. I have installed both GMU11 and archer in the rt wingtip with no issues. |

The answer is, Do you prefer to land slightly left or slightly right of centerline when shooting an ILS? -:)

Your Magnetometer does not care about your receive only nav antenna made of aluminum, it is not magnetic. LH or RH up to you.
I vote for the rear deck under rudder -OR- somewhere behind the aft bag compartment bulkhead. The main issue is get away from steel, in your engine, roll bar... Second or maybe first consideration is maintenance access and ease of wiring. |
