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.

INSTALLATION NOTES

The 50 Ω cable between antenna and diplexer should be kept as

short as possible (preferably not over 1 m).

Some communication antennas have insufficient height to ensure

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

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).

PROCOM A/S reserve the right to amend specifications

without prior notice.
