Sir, I am very pleased to provide my review on your product. First, this product did the job of amplifying my satellite signal. so it works. Unfortunately, I'm not sure it was really necessary. Just not smart enough to provide that answer. As stated, it did amplify the signal but the quality signal strenth went down to the point where it made the picture go away. Maybe I'm doing something wrong. The distance between dish and receiver is approx, 30 meters. The signal increase about 24 per cent (from 69 to 92) but the signal quality went drastically down. So you do have a good product. If possible, may I ask if your technicians are able to assis on why the quality signal went down so much. Inadvance, thank you very much.
