Don't rule out VHF for your OTA Signals !!!

I am adding "three" new UHF only yagi's in the attic. I have visited www.antennaweb.org and got my coordinates and now I am ready to aim.

As a point of interest, antenna web also listed the charlottesville & virginia beach stations too but they weren't shown as Digital. I thought that's odd... va beach is a bigger market and the network affiliates aren't Digital? I decided to find a zip code down there (I used www.usps.gov and plugged in main st, virginia beach, va) and search that area.

The three majors (ABC, CBS & NBC) all broadcast between channel 2 - 13. They are about 75 miles from me and my VHF 210 (supposedly 210 miles but only at 3am can I get Philly Stations from Richmond) has always gave me great signal from there via the analog broadcast.

I am heading to the attic to tweak FOUR antenna now. I'll let you know what happens but I don't think I am going to trash the BIG BEAST just yet.

And don't get rid of them! I look forward to the day when the analog broadcasts are history and the digital signals will be down in the VHF realm where they should be easier for everyone to receive well.

My brother is in Va. Beach and gets the locals digital OTA

I just plugged in the Zip Code for Va. Beach-23451

Many, if not most, stations that are broadcasting analogue TV on VHF and digital TV on UHF have opted to stay on UHF after they shut off their analogue transmitters for good. In some areas VHF broadcasts will disappear completely. You need to check what the individual stations in your area will be doing.

UHF is the better route for digital TV signals.

Are you saying that broadcast stations are giving up on folks getting their signal the old fashioned way, via antenna!? I certainly hope that is not the case. UHF is by definition very "line of sight" dependent as opposed to the longer wave lengths of VHF which follow the curvature of the earth much more readily and as such can be picked up at greater strength much farther away. Great for a straight beams to a flat metro area but horrible for someone over the hills 50 miles away. It also requires much higher station power to cover the same distance. I could see this helping with interfering signals between adjacent broadcast areas but I was unaware of any advantages of the carrier wave length itself. Also, I believe virtually all of the UHF band will eventually be auctioned off to the cell companies as they covet those very short range tendencies that radio and TV do not. The upper range of the band already went to them several years ago. I pity those who live in the hinterlands if this occurs :(

Only channels 52-69 are being eliminated, effective February 18, 2009. From that date on, 49 channels will be available for OTA TV broadcasting : 2-36 and 38 to 51. (37 is not used for TV broadcasting in the USA).

The post February 2009 channel assignments have already been completed and are listed on the FCC web-site. You can check your area there, or contact the individual stations.

The only major station in DFW I found to have made the election was channel 11 and they have elected to go back to 11 once the analog stops. Hopefully the rest will follow suit. Here in TX they have much larger areas to cover compared to the more dense population centers back east. If anyone knows how channels 4, 5, 8, and 13plan to go please share. Thanks.

Actually the election process was completed last year. The results for all rounds of the process were posted on the FCC web site after each round, and a "final" list was also made available for download.

UHF antennas are far smaller as VHF antennas are so big an clumsy. HDTV should not be considered old fashioned.

In DFW channel 8 digital is already VHF broadcasting on channel 9. They will go back to channel 8 after 2009. Channel 11 digital is as you say going back to VHF 11. Channel 52 is going to channel 9. All the other stations (including 4 digital and 5 digital ) are staying on their currently assigned UHF channels.

VHF-lo requires very large antennas to get decent reception, and is also very prone to interference. Only a few stations have opted for VHF-lo (2 thru 6) and the FCC would probably rather they changed their minds. Some stations whose traditional VHF channel is in VHF-hi (7 thru 13)are moving back to their VHF assignment, but most stations are staying on their UHF digital channel assignment.

You guys make me snicker talking about "big ugly antennas" like they are junked cars sitting on your front lawn. Time was a nice antenna or two showed you were technologically with it. Now everyone worries it will mess up the smooth lines of their McMansions. You of course, realize that all this really does is give the stations much more leverage to stick it to the people by charging the cable and sat providers for carrying the HD signals that you should conceivably be able to receive for free. I guess this is their way to get back at Uncle Sam too for forcing all this on them. Televison stations actually do have a higher social mandate than just showing a profit for their investers. Check out the license renewal process if you don't believe me. : (
