General Discussion / Re: Antenna Location & GPS Input

Thanks, guys, for all your replies. I was just about to reply to Peter and Ian and thought I'd got it straight but now I've been thrown a tantalising morsel by Lee
My plan would be to mount the unit behind the panel both for ease of power supply and connecting to the EFIS units. I don't know if the PAW installed GPS would be effective from that position (glareshield above, bits of radio etc either side and the panel's metal and engine to the back and front) but that's not a huge deal; I was simply trying to get away from having another GPS antenna on top of the panel if I could. They're only tiny, so it's wouldn't affect the price of fish but it's my OCD playing up again.
The aircraft I am considering is the Eurofox (lovely looking little things) and I would imagine the antennas, if mounted inside the fabric, would be halfway down the fuselage (ish). I was quite happy to accept Peter's advice about the cable length but it would be good to find out if Lee's proposal may alleviate the problem. If not, then would the area beneath or just to the rear of the seats (below the baggage area) be the sort of place where you'd mount external antennas. I was looking at the tuned monopole whip in the shop. Would you use one of those for P3I and one for ADSB or would it just be one for P3I and the normal ADSB aerial could live inside?
If you think this level of questioning is bad, can you imagine what it will be like when I actually get an aircraft and my PAW kit
