External aerial for the Aera 500.
I bought the GA25 MCX external aerial, to see what I could do with it.
I think it is designed for car roof-tops, and so it is magnetic, and I don't want to put magnets near the compass or even the instrument panel.
Peeling off the plastic film, and unscrewing the four corner bolts, the back plate lifts off to reveal two bar magnets, which are easily removed. Replacing the back plate and film leaves a non-magnetic external aerial. You do not need to open the actual sealed unit.
It seems to work fine. Can anybody see any drawback to this? I can't imagine the magnets improved the satellite reception, and this is obviously better for the compass!
