TolTol,
Interesting. I was taught to fly them, not fix them
The aerials are generic and not specific to the Arrow. That's down to the make/model of avionics installed in your particualr aircraft. Although, the Arrow I did my test in has a GPS, I did not need to know or demonstrate any knowledge of it (I'm sure can hear IO540 gearing up in the background
)
Anyhow, good luck with the test.
