LH 108/136 AMP
Diplexer for Mobile Telephone (136 - 1300 MHz) and Car
Radio (0 - 108 MHz) with built-in low-noise amplifier
DESCRIPTION
Diplexer for simultaneous operation of mobile telephone and car radio
on a common mobile radio antenna.
A single diplexer covers all communication bands 136 - 1300 MHz.
Built-in low-noise SMD-equipped amplifier in the car radio section gives
freedom of choice of mobile telephone antenna.
Better reception of car radio signals due to the built-in low-noise
amplifier.
Power supply of the low-noise amplifier via the car radio cable or by
direct wiring.
Extremely compact.
Quick installation using dual-adhesive pad provided.
FME-connections on antenna and mobile telephone terminals
CRC connection (M10 x 0.75) on the car radio terminal.
Power supply 12 V to the low-noise amplifier via CRC-connection.
Procom 75 Ohm car radio cable available as an option.

INSTALLATION NOTES
The 50 Ω cable between antenna and diplexer should be kept as 1.
short as possible (preferably not over 1 m).
Some communication antennas have insufficient height to ensure
2.
satisfactory broadcast reception. Only antenna whips with a height of
at least 25 cm are acceptable.
Tuning: The antenna is tuned for best SWR at the operating
3.
frequency as usual. The filter is factory-tuned and ready for
installation. The car radio is tuned for optimum reception on the MW-
band by means of the antenna tuning screw (if present).
