Dan & leszek1, thanks for the help. I looked on TV Fool and saw that I am in the purple zone for most of the stations. The HBU 33 is not listed for blue or purple on the manufacturer's website, but the larger HBU 44 and 55 are (if using an amplifier). Do you think the HBU 33 will do the trick or will it be extra insurance to go with the 44 or 55? These may be new antennas, as I did not see any user reviews (vice lots for the HBU 33), so maybe unproven in real world performance? Also, should I go with an amplifier (and if so, which one?). Again, many thanks for the help.
