[Antennas] How to break a Faraday GRID?

2003年6月10日 15:54:59 -0700

Awhile back someone was talking about a 'passive repeater'. Others 
mentioned the use thereof in an office and in a house below the horizon to 
the main repeater. If you house is a FG then maybe a passive repeater 
would work. The only point would be that the bandwidth may not be too 
great. I have never used one so maybe someone can comment.
Put an antenna for Rx on the roof, run the wire into the house then put an 
antenna where you will be having the receiver. Some clain that this will 
work for cell phones in an office.
Donno?
