    Found that since I get my internet from my cable company, it looks like they do not have a filter so am able to get basic cable service from them..

    Since I have an HR24-100, Would an AM21 work as an alternate way to incorporate local channel service for me?

    Most likely it won't.
    Cable would need to send your locals on the exact same frequencies as the stations transmit on, which most cable services don't do.

    The AM21 is designed to receive over-the-air signals and is not compatible with cable.

    Well there goes that thought.....

    Well, can always plug cable directly into tv as a workaround for the superbowl if whdh doesnt come back....

    Depending on how close you are to Boston, you should get your locals with a simple off antenna and an am 21. Are you using an HD tv set? I am in the Roslindale section of Boston and I get WHDH with great signal with my basic indoor antenna. Good luck

    OTA broadcasting uses 8VSB for digital broadcasting while cable uses QAM. The AM21 does not contain a QAM tuner only an 8VSB. Comcast in our area does not pass the 8VSB signal on the cable, they remodulate it as QAM with the channel remapped with your local channel number. Thus local 2.1 is 2.1 not 182.12.

    When I lived in Haverhill, MA I was able to use a roof-mounted aerial to get a few channels. Reception wasn't always great but they have a lot better antennas now.

    I just Love my OTA Antenna!

    Last week we had a Tornado Warning with the Storm moving directly towards my area and my Directv went out due to Rainfade and I switched over to my OTA Feed via my AM21 and I got Perfect Reception of Channel 5-1 Reporting the Direction and ETA of the Storm.

    Thankfully the Tornado did not surface but it was Nice to be able to Monitor the Storm via OTA and my AM21.

    I have always maintained that both cable and satellite subscribers should have a basic capability to view OTA during emergencies and outages, even if its miniature UHF loop hooked to the TV's antenna input.

    This past weeks storm was so intense here, it knocked out the DirecTv signal, even with a 1 meter dish, was even causing lightning flash outages on OTA (and Im 15 miles from 1MW transmiiters with line of sight, and a 17db gain yagi antenna. It was still watchable, and the information was useful. I also can listen to the local Ham radio spotter repeater, as well as the local fire department on scanner, and have a S.A.M.E. weather alert radio.

    My sympathies go out to those in Alabama (again).

    My Sympathies as well as those Storms headed for my area in Peachtree City, Ga. came from that Storm in Birmingham, Al.

    It reminded me of the Tornadoes that Struck Tuscaloosa, Al. and Lake Martin. Al (which was not reported much on TV because Tuscaloosa was worse but there was a 6 mile stretch which was 1/2 mile wide which damaged over 50 homes).

    It got near me too (about 30 miles south) and destroyed quite a few homes, and a country club in Fordyce, Ar. here is a link to some pics I posted during the storm, including our local OTA radar showing the tornado and tracking its progress...
