    VHF hi or low? VHF channels are split in two bands 2-6, 7-13 (real transmit frequencies, not the advertised channel); their frequencies are significantly different from UHF and your antenna needs different size elements to cover them effectively. A lot of "HDTV" antennas assume everyone moved to UHF and only cover that band effectively. You might also consider location and transmitter power changes, but the answer, if there is one, is "more antenna."

    Some of the stations have to install a new antenna, so temporarily they are using side-mounted antennas that don't have the range of their full antenna. That is happening to those of us in the Nashville area with CBS. They estimated it will take up to 2 weeks to get their new antenna installed and running. This may be happening in your case too.
    You may want to check the stations FaceBook page to see if they are saying anything about their antenna, or that they are running in a low power mode for now.

    The channel moved to VHF high. My antenna is a large outdoor antenna in the attic on a rotor so I can adjust it remotely at the TV. I already have one VHF channel for many years that moved from UHF back to it's original channel when they shut down the analog channels. Had issues with that channel for several months until they got permission to increase the strength of the frequency.

    Reorienting it how? The station's antennas haven't moved I assume and I had it directed towards them.

    Not good is an understatement, for OTA around Chicago, at least with Tivo. There are many antenna only channels around here. With all the movement a rescan will find the new frequencies in most cases but Tivo is showing no program info for many. Even ABC, fortunately I don't watch much ABC. Too many for me to write to Tivo, will just hope it straightens out over time. One channel I watch is gone completely, see below.

    Ok I guess there is a law that stations have to broadcast a digital signal through the air. One of my stations is gone after the repack so I looked into it (Comet and all the WRJK subchannels). Supposedly it is "back up". But I don't get it with channel scans. Why not? Further research found they moved WRJK from UHF frequency 24 to VHF frequency 11. And cut transmit power from 15000 watts to 400 watts. Hmm, might get it if you are in the same building as the transmitter? What I am wondering is this, the law says you have to broadcast a digital signal. But in "todays world" almost everything has some sort of payment required, cable/satellite, streaming etc etc. I wonder if this new low power (400 watts?) and crap*y frequency is a way to stay within the law of having to broadcast OTA but make it pretty much unusable so you have to stream or use some pay service to get it. If so I wonder if this will be happening with more stations as time goes by. Maybe I am off base but for me for now goodbye Comet/WRJK around Chicago, I really don't want to watch on the website or pay to stream.

    Lower frequencies require/need lower power to get the same distance as before. They got paid more from the feds for moving all the way down to VHF. You need a high vhf antenna to receive them now. Window mud flap antennas are pretty much only UHF

    Yeah, around Chicago CBS is on VHF high (12). And can be iffy sometimes OTA. The other major networks are UHF frequencies and very strong. The latest repack did not affect CBS, I was hoping they'd move it to a UHF frequency but no. Other major networks moved from one UHF frequency to another but signals are still good.

    CBS is high VHF (12) for me. Can be iffy but is mostly ok with my current antenna. This new WRJK thing though, VHF high 11, nothing. Even though lower power required for VHF 15K watts to 400 watts, is the watt savings that much moving from UHF 24 to VHF 11? Good info by the way, always wondered why CBS was high VHF by me, getting paid by the Feds explains that I think.

    Well, 400 watts seems pretty low. But I don't know the details. Are they a LP (low power) station now, or moved antenna sites? You need to do a little research and find out.

    I think there might be a new antenna if they switched to VHF. They could also be broadcasting at reduced power. I would try rotating the antenna a few degrees each way.

    The FCC pays a significant amount of money to a station if they move to VHF depending on the size of the market. I'll bet the station that moved to VHF received millions of dollars because of the size of the Chicago market.

    Found out they are both still UHF and are both back at full power now. Looks like it's only affecting ABC now. I'll try repositioning the antenna, but I'd be shocked if that has any affect since they came in perfect before the repack.

    I’m on Comcast in Essex Junction VT and I’m seeing some CBS and possibly other guide data issues. Today was the day the new WCAX tower in Mt Mansfield was turned on with a slightly diff frequency. I submitted a lineup report. Is there anything else I can and should be doing as a cable customer? Should I be doing a rerun of guided setup?

    I love when I can get pertinent info from people in the know that I can then get over to TiVo/Rovi.

    Within an hour of my tweeting to WCAX in Burlington, VT, the VP and GM of WCAX replied to me on twitter:

    Even if your cable provider had to make a change in their equipment on their end, it shouldn't have impacted your Guide data. Assuming, of course, your provider didn't also decide to move the station in their lineup. That would be a completely separate issue from the repack, though.

    As a cable customer - the repack shouldn't have any impact on you. That's an OTA concern. What about your 'guide issues' lead you to believe it's a repack issue in your cable listings?

    So we have a another TV hooked up the same antenna via splitter and has no DVR. The antenna is hooked straight into the TV and I saw no pixelation so it seems like it's somehow my Roamio OTA. This is really annoying.

    Thank you. That’s what I thought, but I just couldn’t get the right words out. I have submitted issues to TiVo regarding incorrect guide data. I’ll just have to watch those and make sure they’re adressed overtime. Meanwhile I can always do manual recordings for critical things I don’t want to miss.

    So, it's a new situation with the station move. Perhaps the new antenna they switch to isn't aimed as well as the old one towards your direction. Hook the antenna directly up to the Roamio, and see what happens. Could be the signal level is borderline, and the splitter cuts off just a little too much for more than a single tuner.

    If that works, either get a separate antenna for the Tivo, or get a preamp booster between the antenna and the splitter.

    The station is 4 miles away. Isn't it more likely that the signal is too strong if anything?

    Also, the splitter is outside my house, so would removing the cable for the other tv from the splitter work for what you recommend? Running a direct cable would be way more work.
