A few years ago, I spoke to a guy in engineering at one of the stations I currently receive on UHF. He said that, when he installed antennas for people, he always recommended the full VHF combo. I asked him why in the world he would have done that when mostly all channels were on UHF? He said that he cold not get into details about what he had been told by his boss, however, most channels that were once VHF had kept their VHF broadcasting antennae, just in case the FCC were to sell some of the UHF frequencies, making the UHF channels go back to VHF. He also explained that, although the signal was not better on VHF, due to terrestrial interference, that they could broadcast further for the money because they were paying $3,000 per month to the electric company for putting out the signal that they were broadcasting. He also told me that his station sent their signal directly to most of the cable providers in the area via fiber, just incase the tower were to go down. This statement made me think that it was just in case they decided to quit broadcasting all together. Is this what is coming up? Are channels going to sell their UHF frequencies to wireless providers and either stop over the air broadcasting all together or maybe move to a VHF channel, just to say that they are still broadcasting, but not as many will be able to receive their signal?
