Thank you both for the comments/suggestions.
Apart from the c5, which is a bit more pricey than the Db4, would the db4e be just as good? Seems to have this wider beamwidth than the previous db4 model. Any other models i should consider? Someone from the Digitalhome site mentioned using a Channel Master 4221? That person is about 20km away from me...seems to say he gets good reception...
I mean, can i really go wrong choosing between any of those antennas? (db4, db4e, c5, 4221)
Thanks again. This should be my last query!
