The HDB91X is a really good UHF antenna. I have one in a indoor storage room aiming at Southfield, MI area, where most of our DTV transmitters are located. Distance is about 25 miles. Pulls all of the UHF solid as a rock including our Ion affiliate which is on lower power leading up to repack.
Thanks for recommendations, I was looking for a tuner, xmtr towers are in 2 directions, ENE and N, about 15-18 miles. Due to repack, stations now on lower frequencies come in better than before. TV signal from 2 stacked bowtie antenna runs thru amplifier then 4 way divider to 4 rooms in home. I also have a converter box for old analog tv, almost no multipath distortion and better sensitivity than dish network 211k receiver built in tuner.
