I ordered 3 antennas and 1 amplifier. They absolutely do not work as they are described. Only opened one box to try on one tv. Not at all satisfied so called the customer service phone number many times during different times of the day and chose different options in hopes of reaching someone. No luck at all. The automated message tells you no one is available to help so leave your phone number and name, someone will return your call. Did this, no luck. Complained on their web site. No luck. The name on my credit card transaction comes up as clearancesales.biz. I've read other reviews on several other sites all with this same phone number. I'm out 125.00 for this useless piece of work.
