    It almost never works. I don't think it matters even if you have a great antenna. All other ota channels work fine.

    Re: channel 5.1 des Moines ota channel

    Low VHF (channels 2-6) is a bugger because it is very susceptible to many types of noise and other problems. The ATSC broadcast standard used in the US is not great at dealing with certain kinds of noise and interference.

    When ATSC was being developed, it was thought that low VHF was going to be allocated to something else. However, the money-whoring FCC instead decided to reallocate the UHF channels above 51 because they could make a bunch of money by auctioning that spectrum off to the wireless industry. Thus, some channels will have to move back down to low VHF.

    Regarding antennas, low VHF requires the longest radials for reception. To cut costs, some antenna makers cheat; they claim that their antennas support VHF, but they really don't support low VHF. If you are buying an antenna for low VHF, carefully research the antenna to make sure that it really does support low VHF.

    Back in mid 1970's during the CB craze, channel 5 took a beating. The third harmonic of the CB frequencies lies right in the channel 5 frequency range. Anybody talking on a CB would disrupt channel 5 for a block or so...several blocks if it was a base station or somebody who had illegally increased the power on their CB.

    But it was all worth the CB interference as long as the Bandit and the Snowman. could run that tasty Coors beer across state lines.
