varied reception problems
Hi;
I used to get great TV reception from my roof antenna (on a a 'cable-ready' HDTV purchased a few years ago), as well as from rabbit-ears on an old analogue TV with a HDTV converter box, until FCC required general transmission upgrade which was made. Since the upgrade, I have a number of reception problems with which I hope you can help. I should mention that I live near the Hudson River, and close to a very large bridge (Verrazano). My report is located at: http://www.tvfool.com/?option=com_wr...d24366ec475690 Specific problems as follows. 1) The rooftop antenna with the HDTV fails to get adequate signal on channels 66.1, 13.1, and 50.1, for which there is good signal strength present on my HDTV converter box/ analogue TV. On those channels which I receive clearly, there is never any intermittent loss of strength or interference present. 2) On my old analogue TV, I receive all local network channels (including the ones mentioned above), but every time a boat travels on the river ~150 ft. below me I get interference or complete signal loss. I'm using a Radio Shack "amplified" rabbit ears, with a Zenith converter box. Any suggestions to help these problems? Thanks for your attention. |
The signals in your location are too strong for you to use an amplified antenna. Find your old unamplified rabbit ears.
Your rooftop antenna cannot be aimed at the signals from the Empire State Building and 50.1 and 66.1 at the same time. I'd assume that it would work if it were aimed toward New Jersey instead of Manhatten. I don't know why 13.1 isn't working. |

Also, do you think that 13.1 may improve if they ever switch broadcast to the Freedom Tower? |
The passing cars/planes/boats phenomenon is pretty common. If my antenna is mounted near ground level, the signal breaks up every time a cah drives past on my street (seldom here). Certainly the large passing metal object changes the propagation of radio waves (and TV) locally, but the exact nature of the change I'm not sure. I'd guess the big metal object is reflective and it creates multipath interference. Might help to put your antenna higher, like on the peak of your roof.

I'm most puzzled by the signal degradation that this new HD technology has resulted in, since once they had upgraded the standard broadcast signal some 15 years ago (I'm not technically savvy, but I think they added some kind of 'rotary' signal transmission in order to minimize interference at that time), the channel reception used to be perfect. At least, luckily, I don't seem to get interference from cars, of which there are many. Sounds as if there's no hope other than to use the cable-tv rapists, with their "thousands of channels and nothing to watch" pricing policies. |

Incidentally, 31 degrees magnetic is approximately NNE, if you want to try re-aiming first. |
Thanks; Shall do.
