I was wondering is it worth getting a ITELITE DBS antenna over a RE700 extender ? I have a RE500 now and I'm not sure about the boost in range I will get with ITELITE DBS atennas ... could a single RE700 be better compared to the setup I want to make ? (RE500+ITELITE). Buying RE700 + ITELITE is out of the question since I don't want to spend that much. So my bottom line question is: Should I get a RE700 to replace my RE500 or I should get an ITELITE DBS Atenna for my RE500 ? Thanks !
