I am living overseas in a high-rise apartment. I receive satellite programming via AFN (Armed Forces Network). The country that I am in does not allow satellite dishes so my dish has to live inside of the house. I have a small dish (Direct TV type) that is mounted on a stand. I used to get great reception even though a window sits between the dish and the outside world. Well about 3 months ago the provider changed transponders and now I can only get a signal if I open the window. Will an amplifier boost my signal enough to allow reception through a window??? Thanks much.
