VOR/ ILS
We have a single aerial for the VOR/ ILS and the VOR works fine. We havent
had the opportunity to test the ILS ever. Its a copper tape dipole aerial
mounted horizontally inside the rear fuselage og the AC. (I have loads of
spare copper tape if you want to experiment).
Personally I cant see the point of having ILS (or VOR) these days on an
aircraft like a Europa. GPS does the same job better and its even possible
to have pseudo ILS on your GPS receiver that will be nearly as accurate.
My understanding is that unless you can test and callibrate your ILS
receiver you could never rely on it in a real life situation.
