[Color Zone] Green [Antenna Type] 
Medium Omni/Multi-directional antenna is required in a green zone. In a green color code area the signal is slightly weaker and a bit larger antenna is required. The signal in a green area may be strong enough to try an amplified indoor HD antenna if you have one. Remember, however, that with an indoor antenna nothing is guaranteed. Only outdoor antennas can be certified for any particular color area.
