2.5 Antenna Installation
2.5.1 Outdoor Antenna
Select a site for your outdoor antenna, making sure you have enough signal strength
at that location. Using coax cable, connect the antenna to the repeater. If you are
using a directional antenna such as a Yagi type, the antenna should be installed so
that it is in line of sight of the base station. Then, align the directional antenna
toward that direction, and secure the antenna using provided mounting hardware.
Use of a lightning arrester is highly recommended. By installing a lightning
arrester between the outside antenna and the repeater, you can protect the repeater
unit from electrical surge from lightning.
2.5.2 Indoor Antenna
Install the indoor antenna at a convenient location. It should be free of metallic
obstruction in order to have an effective coverage. Depending on the circumstance
of the installation, either one or a combination of following antennas can be used:
Ceiling mount patch antenna, Wall mount patch antenna, Corner reflector
2.6 Bi-Directional Amplifier Installation
USHR-800NI is an indoor amplifier. Accordingly, the environment of the intended
installation site needs to be considered. The repeater must be shielded from
moisture, such as rain, and excessive temperatures. The operating temperatures
should be between -20 °C and 50 °C.
