Getting Started

Mobile Station Installation

Select the location of the transceiver and microphone bracket before starting the installation. The location should be convenient and should not interfere with the driver

or passenger in the vehicle. The transceiver should be securely fastened to a solid face, using the mounting bracket and self-tapping screws which are provided.

Choosing an Antenna

Since the maximum allowable power output of the transmitter is limited by the Spectrum Management Agency (SMA), the antenna is a very important factor for transmission distance. For this reason, the installation of a quality antenna is strongly recommended. The SundownerUH-O99 is a superior transceiver, however, installing an inferior antenna may cause a reduction in performance.

Only a properly matched antenna system will allow maximum power transfer from the 50-ohm transmission line to the radiating element. Your Uniden dealer is qualified to assist you in the selection of a compatible antenna to meet your application requirements.

For automobile installation, the whip antenna is recommended. The most efficient and practical installation is a full quarter wave whip antenna mounted on the rear deck midway between the rear window and bumper.

A short "loaded" whip antenna is easier to install on an automobile. However it is not as efficient as a full quarter wave whip antenna.

For marine installation, consult your dealer for information regarding an adequate

grounding system and prevention of electrolysis between fittings in the hull and the water.

Ground System

Connect the red DC power cord from the transceiver to the positive (+) battery terminal or another convenient point and connect the black power lead to the vehicle frame, or the negative (-) battery terminal.
