It's more than just YES unfortunately. NY actually have 4 RSNs, YES and SNY, plus 2 MSG channels. MSG is also not offered on YTTV. The only reason I cut the cord in the first place was because there was FINALLY a full featured OTT that has all 4 RSNs. Plus, if it was just me, rotating among the various OTT services wouldn't be a big deal, but I have other people in the house where I'm trying to make things as easy as possible. Even THIS solution is not as intuitive as having everything in one place.A classic streaming dilemma. The antenna idea is good since it gives you flexibility. You want VHF elements since WPIX and WNET are high VHF signals. Another viewing method for PBS is the streaming apps offered by NJ PBS and WNET and WLIW. YouTube TV offers Connecticut PBS and WLIW and WNET in the NY Metro area. With no contracts you could go with Directv Stream during the baseball season and substitute the lower priced YouTube TV during the baseball off-season. There is a possibility that YES will be offered direct to consumer next season but I think it is less likely to be offered than the fully owned Sinclair RSNs.
I put up an antenna over the weekend and bought HD Homerun to "stream" the OTA contents via Channels. Works decently and no change in reality to what we were doing before (and in the long run, save another $5). Still need to tweak the antenna some, but that's next weekend's project.
