[Color Zone] Yellow [Antenna Type] 
Small Omni/Multi-directional antenna is required in a yellow zone. Yellow zone is where the reception conditions are the best and the signal level is very high. Typically, the yellow color code area is very close to the transmitting tower. Although the color coding is used to classify outdoor antennas only, if you are in the yellow area there is a good chance that an indoor HDTV antenna (and even better an amplified indoor antenna) will work very well. If you have one, give it a try.
