Poor/No reception in new house- Xistor radios too

The outside TV tech (who was the tree climber) had just installed an outside TV antenna and a satellite dish and called the shop. "No reception in the house for radio" "You need to come and figure this out".
So I had a service call to these folks. They were favorite customers of the store and really great people. They had just finished their new home and had extremely poor radio reception in the house, EXCEPT in front of a window.

Turning the radio different directions made no real difference in signal. No real reception.

It took a bit of thought on my part. (I had done some remodeling years before with different types of insulation).
 AHA!! EUREKA! I looked at them and asked the dreaded question:
" Did you use FOIL BACKED insulation when you built the house?"
 Answer was 'Yes, we did".

So they basically encased the house in a Faraday Cage. I explained this to them, and we installed a vertical long wire antenna outside and ran a lead in to the house, then added a large wire loop to distribute the signal. Problem solved.

This same problem can also occur with metal shell mobile homes.

 Sometimes you gotta think out of the box for a solution.
