Is it possible to receive RFD on a smaller dish like a 1M Primestar or a 1.2M dish? I want to set up a FTA for my dad and he would like to receive RFD. The only problem is that mom does not want a BUD in her backyard!!! I was wondering if RFD signals come in strong enough to even consider a small dish before I play around and find out the hard way that it might not be possible.
