A CW channel in HD in the Lincoln-Kearney market, for Supernatural. There's NO CW at all in this market, used to be one, albeit in SD
If you cannot pull in a CW affiliate OTA, then you may want to see if you qualify for superstations. If you qualify, you could pick a CW affiliate (like KTLA, WPIX, and KWGN...you may want to check the TV schedules before choosing on a tv listings site like Zap2it, Titan TV, TV Guide, etc.) or however many you want that are offered for $2/month each, or you may pay $7/month for all five superstations (I believe WSBK and WWOR are MyNetwork TV affiliates). I am not sure if Dish can "import" an affiliate from another market free of charge; it probably would not hurt to ask or to request.
You may check if you are eligible for superstations on your MyDish account or on the following site:
