PAR-820R LTE PROTECTED
The PAR-820R LTE PROTECTED SAW tubular TV preamplifier is an improved version of the PAR-820 LTE PROTECTED SAW amplifier in which, in addition, the input and the output have been swapped, allowing the preamp to be installed directly on outputs of theT-urbo-T and DIGIT antennas and output of the ZWR-210DC antenna branching filter. The preamp is used to amplify weak terrestrial TV signals received by a passive antenna. Thanks to the SAW technology, the preamp eliminates the LTE800 signals and does not remove the DVB-T signals.
The preamplifier’s casing design allows its assembly in any point of coaxial antenna cable. This means that the preamplifier can be used in the existing antenna system without the necessity to disassembly the antenna. Due to deterioration of the signal/noise ratio along with increase of distance from the antenna, it is recommended to locate the preamplifier as close to the antenna as possible.
PAR-820R tubular preamplifier is designed for indoor use. The device is supplied through a coaxial cable from the output side. Due to wide range of permissible supply voltage (5-24V), the amplifier can be supplied directly from tuner or TV set (those devices must be able to provide DC 5V voltage), or through an external power supply separator (together with power adaptor).
The LTE PROTECTED version includes built-in SAW technology (sharp edge & depth filtration).
