According to antenna web these are the color codes for the digital channels. Fox - Green. VHF 56.1. Compass 245 Miles. 22.6 CBS - Red. VHF 27.1 Compass 274 Miles. 23.8 NBC - Red. UHF 18.1 Compass 273 Miles 23.4 ABC - RED. UHF 36.1 Compass 273 Miles 23.4 My antenna I currently have has no problem picking up both UHF channels. ABC & NBC. They come in great, with a very high signal strength. However, for the life of me I can not get the VHF channels to come in with my current antenna which is the RCA ANT 706A. It says it's supposed to pick up both UFH & VHF. I've tried doing the dance around the roof pointing every way I can and I'm having no love with the VHF. Today I ordered the Antennas Direct DB4, and it says tt will pull in all UHF frequencies and most higher level VHF frequencies with a range of about 55 miles. What is considered a high level VHF signal? Does FOX 56.1 or CBS 27.1 qualify as being high? If this antenna does not work out do you have any suggestions? Thanks.
