gossamer,
The network affiliation shown in the TVFool reports is for the main channel only, not the x.2, x.3, etc. subchannels. For low-power and independent stations that run many subs, its tough to have up-to-the-minute accurate information, so TVFool may leave that field blank. John was trying to point out to you that there is some programming available in the VHF Lo band, albeit special interest. There will be two other low-power stations that will be available in the future according to your report, one on channel 4 and one on channel 6. Do some searching at rabbitears.info to see if any of what they would have to offer might appeal to you.
Otherwise, you should go with the UHF/high-VHF antennas from Antennacraft and Winegard that @GroundUrMast recommended.
At the risk of spinning this out of control, I think your friend was confusing a couple of issues together. He was probably thinking about problems that can happen when HD receivers (either in the TV or as a separate box) get overloaded by nearby FM stations. In some cases, strong FM stations can set up interference in the high-VHF band that KOs reception of those particular stations. Strong signals of any type (FM, low/high VHF and UHF) can overload the receiver and cause interference all up and down the dial or simply force the tuner to scale back sensitivity and lose reception of weak stations.
I'm not sure if you remember FM radios in boom boxes, but if you got one near a broadcast tower, you would start to hear that station on multiple locations on the dial. That is a similar situation to what I was describing in the last paragraph.
