Problem solved

2nd TV is now receiving the same amount of channels as the other TV. Both have a sharper picture. Good quality product. Thanks

Reliable Strong Signals

I don't like to write reviews soon after purchase. We have used our Mini-2 for a few months now, and it works like a champ, providing strong signals to our two widely-separated TVs in spite of the long cable from our attic yagi antenna to our basement Mini-2. It uses the traditional funky power-thru-cable connection to its power supply, and the power supply has a bright green LED when connected to 120V AC. I found other splitter/amplifiers to be unusable, so am very happy to have one that works.

mini 2 is great

unable to split signal without loosing channel. The adding of a mini to split incoming signal worked well. NOW i have TV in 2 rooms WITH NO LOST CHANNELS.

Great Little Spliter

I have an extremely long run from my antenna to my 2 tv's. It's over 100 feet. The spliter that I put in to run to an additional tv worked for about 1 day and then kept receiving less and less stations. It finally did not get any channels and the first tv was also now getting less channels. So, I went back to a straight run to the first tv - all was fine, but only 1 tv. So, I watched some you tubes and saw info about channel master powered spliter and ordered one up. Got it in 3 days and installed the spliter. At first I now got absolutely no channels on either tv. So, I then hooked up the power to the unit and now I get 37 channels on each set, great picture and reception. I waited over a week to do this review, wanted to make sure it would last. I highly recommend this product. Shipped fast, hooked up easily, and works great. By the way, the transmitter is over 60 miles away in up state NY.

Great device shipped fast

Device works as intended and feels very solid. Made of metal and should last many years. The order shipped super fast and was delivered within a few days. Very responsive customer service. Great experience and will order directly from the company for future needs.
