Tv antennas and Tv reception

Ok thanks for the old and new exact address. . The reception at your new location is not as good because of the ways that the Tv transmissions scatter and bend across the Casa Grande regional park mountains to the north. . At the >Start MAPS< part of tvfool you can test different locations on the property. Move the antenna around and up and down. It looks like the strongest signal for KPPX is with the antenna about one foot above the ground. . 0 NM(dB) is the reference signal power number for reliable reception. Negative 10 NM(dB) is about the lowest receivable signal strength and Plus 4 NM(dB) for KPPX is a weak signal. Antenna gain gives more positive numbers to the signal power. . When the NM (dB) numbers get up in to the 20's , 30's , 40's , 50's , 60's thats better. . GM is correct with the 2 antenna , preamp solution. And for the phoenix stations the antenna or antennas will need to be pointed at the tops of the mountains to the north. Also do not block the front of the antenna or antennas with fences or walls or buildings. The antenna/s must be free of obstructions. Probing with a antenna or antennas is the best way to find hot spots on the property.
