toadcat,

NTE ECG U-106 Rotor vs Radio Shack 15-1220
tripelo,
No comparison. The Radio Shack 15-1220 is a 5-wire rotor that uses a balanced bridge for exact positioning. In the 50 years I’ve used it; it has never gone out of alignment. It...

Yes, but just barely. The PCT MA2-M’s are rated @ 2.7 dB average NF, 4.0 dB max. & the Winegard HDP-269 is rated “Average Noise: 3dB”. The AP-2870 is rated “Noise: VHF 2.9...

When I follow your link, TV Fool comes up but your signal report doesn't display. Could be a problem with the site, but mine (from Southern California) still displays properly.
