Terra LF002 R82012 LTE rejection filters are used in TV antenna systems. The filter cuts off the unwanted part of the UHF spectrum (791-862 MHz) reserved for data transmission in mobile networks (LTE). The device is especially recommended for systems with broadband amplifiers covering the whole UHF band (up to 862 MHz). In such systems, the interference from the unwanted signals can completely block the reception of some DVB-T multiplexes. Intended for indoor use.
Thanks to DC-pass (max: 24 V, 100 mA), it can transmit power to antenna preamplifier(s).
Key features
- rejection of LTE band (> 790 MHz)
- very steep slope just above the channel 60
- DC pass (max: 24 V / 100 mA)
