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 FL2833BP is designed to pass through UHF TV channels 28 to 33 (526~568 MHz), also known as Channel Block B, rejecting out of band TV signals up to 50dB.
