I would pay Comcast $9.95/month for this service of utilizing their VHF antennas through the existing connection so I don't have to install an FM roof antenna on the chimney and worry about the grounding (and the ugliness complaints from the HOA and neighbors) and still not get all stations clearly in stereo.
I would like to get KTSU and KACC clearly and KPVU, both in stereo. It could help rimshots like KTHT. This could help with reception of the proposed KUHC in southern Houston since they mentioned that they are going to add boosters in Clear Lake and Katy (presumably at the old K217DP site). KFNC and other Beaumont rimshots could have a spot on the dial, bringing ESPN to the populated western half of Houston.
Imagine hearing KPVU over Comcast Galveston lines or KSHN available metro-wide? It's a win-win for everyone. Carriage agreements could be similar to the broadcast TV stations and the big radio station groups would feed the cable directly from the studios and listeners could enjoy listening instead of fiddling with the antenna (like during tropo events).
