The NBC that we can get here is WESH-LD18 which is digitally broadcast out of Orange City on frequency 18 as 2-3. It is several degrees away from the Orlando cluster of towers, so the directional antenna doesn't pick it up as well if you want all the other stations. I can get it about 90% of the time. Right now I'm getting at a signal strength of 45 for NBC (2-3) where CBS (6-1) is 72 and ABC (9-1) is 59. The VHF WESH (2-1) is broadcast on frequency 11 and a signal strength of 35 but not enough to register.
