Rejection filters Terra LF002 LTE are used in television antenna systems, rejecting the band used for 4G telephony.
What technical characteristics does the LF002 filter have?
- The filter cuts 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 that cover the entire UHF band (up to 862 MHz)
- In such systems, the interference of unwanted signals can completely block the reception of some DVB-T multiplexes.
- Designed for indoor use
- Thanks to the DC step (max: 24 V, 100 mA), it can transmit power to the antenna preamplifiers.
- Rejection of the LTE band (> 790 MHz)
- Very steep slope just above channel 60
- DC step (max 24 V / 100 mA)
