GPS reception and lightning protection

Curious, since these boats are all aluminum, do you get adequate reception in the cabin for GPS and cellphone? Since they are basically faraday cages, how is the lightning protection? Also, do you present a large enough radar return to negate needing a reflector?

Thx, Bob

The glass windows negate any Faraday effects.
GPS and cellular work fine inside.

Lightning is a non issue. It would (in my opinion) be shunted out the hull into the water much easier than fiberglass. But all bets are off with a direct strike.

From what little I have read on the radar subject it does seem metal boats should use a reflector but may want to look into AIS transceiver.

I had to mount an external antenna for my GPS. It would work fine until I turned and the signal was blocked. Cell phones seem to work though.
