Can anyone tell me why I can't get any OTA reception 50 miles away but can get full power for stations 100 miles away? My approx. location 38.256953,-76.479306 -- about 50-55 SW of Wash., DC. I've mounted an 8-bay bowtie antenna up about 15 feet several days ago. Been trying like mad to get DC stations. Once in a while I'll get 66.1 from DC, and 22.1 from Anappolis; both with crappy signal. Or I can turn the ant. toward Salisbury, MD and get 16.1, 47.1, and 28.1 with reasonable signal. Tonight, I noticed 15.1 WHRO was showing up during a scan. I lived in Norfolk back in the late 80's and knew instantly where that was from---just a bit over 100 miles away! My curiosity go me and pointed the ant. due south. OMG! I was getting nearly all the major stations from Norfolk at full power. WTH? Can someone explain this to me?
