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 FL3439BP is designed to pass through UHF TV channels 34 to 39 (568~610 MHz), also known as Channel Block C, rejecting out of band TV signals up to 50dB.
