Applications
Suitable for collective terrestrial TV installations which are affected y the transmission of LTE800 mobile telephone signals in the 790-862 MHz band, and by GSM and TETRA transmissions in the 870-960 MHz band. The filters suppresse interfering signals before amplification of the TV signals at the head-end of the installation, or between the outlet and the television so as to prevent interference from mobile devices, thereby obtaining a rejection in the LTE800 band of up to -60dB.

Characteristics
Shielded zamak chassis, metal-plated, with F-type connectors. Connectors situated at the bottom to facilitate connections. Its compact design means it can be installed in a 100 x 100 mm box.
