I've read a couple of interesting but old threads on here, eg "Homebrew passive antenna coupler" and "Ultra low power 3g repeater"
I'm wondering if it would be possible to boost a modern smartphone's effective range by connecting a decent sized aerial (directional if needed) to a small patch antenna which would be placed next to the phone. This would be without any active amplification.
This might enable better communication on hill walks which otherwise have minimal/no phone cover.
I saw an Australian YouTube item that used "inductive cradles" in a vehicle with an external aerial but it was unclear if there was active amplification.
Would the patch antenna re-radiate the phone signal usefully?
