MIYAKO USA VHF/UHF/FM/HDTV Cable TV Antenna Booster - Signal Amplifier and Distributor - No Gain Control Switch (KF-238)

I have an existing booster, we just needed the dual output. From what we can tell, this provided no boost at all. Signal coming out was equal to what was going in.

Makes almost no difference in signal strength and gives a 60-cycle hum in addition to having a pilot light to show it's energized. Wouldn't buy it again.

Terribol made signal worse.
