Installation of a Yaggi antenna as an outdoor antenna

Cable layout and connector assembly

1. Keep the type, specifications, routing direction, location and curvature radius of cables in compliance with the model

requirements. Place cables in correct order, bend them smoothly, and protect the surface from any damage.

2. Place RF cables separately from power cables. Take proper isolation measures if they have to be placed on the same

cable racks owing to the site condition restrictions.

3. Fasten all connection parts of the whole system in correct order, from the antenna to repeater interfaces, and make sure

that the electrical interfaces are well contacted. Give waterproof treatment to outdoor connection parts.

4. Take lightning protection measures for the antenna and feeder system in accordance with the system requirements.

Avoid deforming the antenna feeder where grounding clips are placed, and give waterproof treatment to the feeder.

Lightning Surge Protector Usage

If the area where you live is exposed to thunderstorms, it is highly advisable to protect a mobile repeater with a lightning surge
protector. Installed in-line between the outdoor antenna and the signal repeater, the surge protector prevents equipment from

damages.

Lightning Surge Protector Setup

Please read carefully the instructions provided with the coaxial surge protector to ensure safe and effective installation in terms of
grounding and maintenance.

1. Connect the male N-connector of the surge protector to the female N-connector of the outdoor antenna.
2. Connect the female N-connector of the surge protector to the male N-connector of the cable that leads to the signal

booster.

3. Clinch a copper wire to the grounding lug and then attach it to a master ground bar or earthing system in order to

ensure low impedance path to ground. The ground wire must be as short as possible and straight. It is essential that the
