The silver sensor almost suffices, but just not quite.
So for the downstairs I got a Channel Master 4220HD METROtenna. It's really just a classic array & bowtie design, intended only for UHF (though it's hard to find that info on the box). I set it up on a mast in my uninsulated porch and hooked it up to the Dish receiver and scanned and i found everything (even the channel 25 streams and channel 56).
Everything came in great--except channel 7-1. Oddly, 7-2 and 7-3 were fine. I thought if you could get one stream the others were receivable. I simply added channel 7 manually to the dish receiver and it was fine.
And, as I expected, no problem receiving the high VHF channels. Everything comes booming in with channel 2 my lowest (65%).
So what's up with 7-1? Was it a matter of the receiver getting conflicting info from the repeater?
Some TV tuners or even converter box tuners don't handle multiple virtual channels (in your case, the Dish Network converter box). WLS-TV is one of those stations that currently maps RF 7 & RF 44 to 7-1 - 7-3 (my converter box uses a "."
rather than a "-"
). I know for myself, both sets of virtual channel 7's show up on my Magnavox DTV box, as well as my VisionTek USB TV Tuner stick, Hauppauge USB TV tuner stick, & my Haier 7" portable TV. In the case of the USB TV tuner sticks, both of those have the software organize the channels by RF channel, though it lists the virtual channels, but list them in RF channel order. For the Magnavox DTV box (model# TB100MW9), it lists the VHF WLS-TV first with the virtual channels 7.1 - 7.3, then the UHF WLS-TV on RF 44 second with the virtual channels 7.1 - 7.3. For my Haier portable TV, it lists the virtual channels twice in order: 7-1 (RF 7), 7-1 (RF 44), 7-2 (RF 7), 7-2 (RF 44), 7-3 (RF 7), & 7-3 (RF 44).
Get prepared in the near future when WBBM-TV signs on their translator on RF 26 from the tower at 4949 West Belmont Avenue (former WXRT studios, & the backups for FM stations: 93.1 WXRT, 96.3 WBBM-FM, 99.5 WUSN, 104.3 WJMK, & 105.9 WCFS-FM). When the translator signs on & you rescan, you either will have 2 2.1's, or your converter box will have a difficult time locking in one of them.
As for what you're getting, I'm amazed that you get WYIN from your location with your antenna. That station is a challenge for some people on the Illinois side (especially for those in the city & northern suburbs). I have issues with WYIN, because low power station WHNW-LD on RF 18 in Gary interferes with WYIN from time to time. Do you get all 4 streams on WYIN on RF 17? If you don't, then it's no big deal, because 56.2 (720p HD) & 56.4 (16:9 SD) simulcast the main channel on 56.1 (720p HD), while 56.3 (16:9 SD) is the only channel that's programmed different, & is usually PBS Kids Go programming.
