I bought a Terrestrial Digital (Antennas Direct) DB8 back in March. I added a clearance amplifier from Radio Shack a couple months ago, mentioned a few threads down.
My balcony faces northeast with the antenna aimed north so I can pull in WGBY, which is PBS out of Massachusetts. It compromises a couple of other channels, but we want PBS more than anything else. It's possible I could get more if I added a VHF antenna, but it's not worth the expense for a second NBC and second ABC.
The channels I actually receive:
3.1, 3.3, 3.4 CBS (RF 33)
18.1-18.4 Univision, Univision SD, UniMas, LA-TV (RF 46)
20.1, 20.2 CW, This (RF 20)
24.1-24.3 PBS, CPTV4U, CPTV Sports (RF 45)
26.1-26.5 iON, qubo, iON Life, Shop, QVC (RF 26) *iffy due to antenna aim
30.1, 30.2 NBC, Cozi-TV (RF 35)
40.1, 40.2 ABC, Fox (RF 40) *iffy during rain/overcast
48 AMGTV, formerly RTV
57.1-57.4 PBS, World, Kids, Create (RF 22)
59.1 MyTV (RF 39) *only in ideal conditions, pretty well blocked by my building
61.1, 61.2 Fox, AntennaTV (RF 31)
