TV via antenna drops in signal strength?
- Thread starter thezak
- Start date
I think we're well past the repack, but perhaps these stations signed on ATSC 3.0 so they moved their current on-air signal (1.0) to a different, weaker channel. Or, it is tropo season, and farther out stations could be interfering with your stations. Or, there's tower maintenance.
I think this would best go in the Boston forum.
Based on the thorough description of the problem, I'm blaming the ghost of Elvis.
What does a "drop in signal strength" mean?

I think he's talking about stations during repack which moved from UHF with higher field strengths, to VHF with much lower field strengths. For example; in his area WGBH moved from "transmit channel" 19 pre-repack, to 5 with 34kW ERP. VHF frequencies are favored as far as propagation goes, but are much more susceptible to interference from terrestrial noise sources.
Personally I think it's a mistake to move from UHF to VHF, but many chose to take the money since most of their viewers are watching via cable or satellite anyway. A wise old consulting engineer once told me: "Kelly, field strength always wins."
Tips and pointers? Buy a good quality outdoor VHF/UHF antenna and mount it at least 30ft above ground level, and not in an attic. Having a rotator on the antenna is a bonus, because you can probably watch other markets too.
Those "HDTV" flat antennas you stick to a window or wall are made for UHF only. They won't receive VHF DTV stations.
thezak,
check out this website, the Signal Search Map part. Move the arrow ( blue mark ) to your approx. location on big map, you can also zoom into your approx. area, of U.S., then click GO, you'll get a list of stations and info on them in your area . . . you can narrow it down better if you know your lat. & lon and enter it manually.
Got to play with it abit, but you'll see how it works.

I understand the definition of the phrase. So I must stand by my diagnosis, that someone wearing blue suede shoes is haunting your TV.
