The Kingray band pass filters are ideal for the rejection of unwanted out of band signals, thus providing a cleaner set of RF signals for distribution. As part of the design, these filters have a rubber o-ring & a rubber seal.

The FL4651BP is designed to pass through UHF TV channels 46 to 51 (652~694 MHz), also known as Channel Block E, rejecting out of band TV signals up to 50dB.
