I may have to use a remote mounted SV-MAG-236 magnetometer for my Skyview system because my trim motor is in the location where the AHRS is located and this motor creates a small amount of magnetic interference.  I placed a compass in the location and the needle moved a little…it might still work however I am thinking up my backup plan.

 

The ideal location for the remote mounted SV-MAG-236 magnetometer would be under the rear seat of my Velocity (fiberglass) however that is where I want to mount my ADS-B antenna.  

 

So the question is…does an digital antenna (and or the coaxial cable running to/from it) create magnetic interference and/or how close to a ADS-B antenna can I locate the SV-MAG-236 magnetometer? 

 

THANKS for your help!!!

Cheers!!!

G’day Bill.

There’s actually no such thing as a digital antenna … every signal (switched digital or analogue) is simply superimposed (i.e. modulated) onto a carrier sine wave at the pre-defined frequency (in this case 978MHz or 1090MHz depending on your ADS-B kit).  It’s more of an art than an exact science and while properly grounded coax in proximity may be just fine, having a radiating (transmitter) antenna that close to the magnetometer is not good.  Dynon does allow an AHRS to be offset from the centreline (by extension the magnetometer too), so perhaps you could install the magnetometer in the wing root?



Cheers, Stu
