I live about 70 miles from the transmit towers in my area and was having a hard time getting consistent reception (frequent breakups and sometimes total loss of the signal for extended periods of time). I am using an outdoor yagi antenna designed for deep fringe reception. I installed this preamp right at the antenna for maximum benefit and used RG6 cable throughout the entire cable run. This preamp made a huge difference. The signal is much more stable now with very few picture/sound breakups. I'm also receiving several stations from the LA area now which is about 160 miles away with surprisingly consistent picture quality. The housing on this preamp is made out of plastic which feels a little cheap and makes me wonder about long-term durability. Otherwise this is an excellent product that works very well.
