There were both up on TW cable ... Never knew they were down till the post.
Yes if affected, WLVQ, WSNY, WCOL, WBNS, The Blitz, and Jack FM.
Last evening, American Electric Power was working on a repair, but Channel 10 officials said they had no estimate for when signals from WBNS and WCMH would again be available over the air.
“I just talked to both the underground and line supervisors, and they’re not sure where the problem is yet,” said Pat Ingram, director of engineering at Channel 10.
The WBNS tower also hosts several radio-station transmitters, including one used by WLVQ (96.3 FM). However, all have backup transmitters and should be working, Ingram said.
WCMH was knocked off the air Tuesday afternoon due to a power outage, leaving viewers in Columbus unable to watch the NBC-affiliate over-the-air or on DirecTV for nearly 18 hours.

OhioMediaWatch said:Most large market TV stations have direct fiber feeds to the major cable companies.
The WCMH/WBNS "hit" apparently hit their shared transmitter site.
Horizon customers Tuesday lost those two channels until power could be restored at the tower location, which was expected to happen by this morning.

This may not apply to Horizon customers in Chillicothe. They lost both WBNS and NBC 4 OTA and on cable.

CHILLICOTHE --
Horizon customers Tuesday lost those two channels until power could be restored at the tower location, which was expected to happen by this morning.

Neither the WBNS-DT nor WCMH-DT transmitters are on backup power. DTV transmitters just draw too much power. With only about 15% of the viewing audience watching "off-air", it was not considered cost effective to install a backup generator large enough to power the DTV transmitters.
All the FM stations, except WRZK are on generator backup. However, shortly before 5pm on Tuesday, the generators shut down due to a fuel problem (air in the system). All the Class B stations transferred to their backup sites. Unfortunately for 98.9 (a Class A), they have no backup site and had to remain off the air until after 6pm when the backup generator fuel problem was fixed.
Back in 1988, WRKZ was the last Class B FM station to move it's transmitting facility to the WBNS-TV tower. As such, there was not enough electrical capacity into the building, so WRZK had their own feed which isn't on either of the WBNS backup generators (there are two). When the underground feed failed at on Tuesday WZRK transferred to it's Grove City backup site and remained on that site until Wednesday morning when AEP finished up replacing several hundred feet of underground cable.
The problem with the power only affected one of the three power phases, a condition known as "single phasing". Of course this affected all the TV and large FM stations which require 3 phase power. However, LPTV and smaller radio stations, which only require single phase power (which is really two phases in this setup), may or may not be affected depending upon whether or not the missing phase is one of the two that they need. This is the reason that some of the LPTV stations (can't recall which) were able to remain on the air. Unfortunately for 98.9FM, the missing phase was one that they needed.
gabigley1 said:There was one LPTV station that was on the air last Tuesday night. It broadcasts from the
WBNS-TV site far as I can tell. It is the HSN station on Ch. 44. LPTV Ch 19 was OFF the air Tuesday night and they are on the WBNS-TV tower.
This is what a Broadcasting Engineer told me about the outage of Radio and TV Stations at the WBNS-TV tower site. Permission granted to post this here on radio-info.com:

xmusicmatt said:I guess the moral of this is when the next big storm hits and WBNS-DT and WCMH-DT are without power... They will not be the 'news leaders' ... Hopefully Columbus never has another major wind storm (like we had a few years ago in Sept) or a severe ice strorm...

engineer for letting me share his email under Quote.
One more thing, do you believe the OTA viewing audience is only 15% of the total viewership? Was thinking more in line of 20%
to 25%.

With the price of cable rising, I think you are going to see more and more people going to OTA. I mostly watch MeTV and have been debating getting rid of cable. Would miss the news channels, though.
CBS or ABC News is left out of cable. They need to have a 24-hour news channel for OTA. ABC probably wouldn't want to encourage OTA for fear of cannibalizing ESPN, but CBS has nothing to lose.
