Have been in a couple of office buildings with metallic coatings (IR
reflective) on windows. Sort of like a large Faraday cage; not much RF
gets in or out including cell and paging. Same situation in some cars
with "Solarshield" windows.
Don't have experience with metal siding, but you're on the right track.
If you don't want to trail a cable, try a passive repeater; indoor
broad pattern or omni antenna cabled to outdoor antenna which has
enough pattern to see repeaters you use; I've seen this work twice. It's
clearly a lossy solution, but is better than a shield.
Other solution is to cob something together with a cordless phone inside
coupled to your stationary rig with outside ant.
