Tsunami MP.11a Antenna Installation Guide

Sealing the Cable Connectors

Most problems associated with wireless outdoor installations are related to degrading performance due to corrosion of the antenna cable and cable connectors. To avoid this type of problem, you must always seal the cable connectors that are located outdoors using the weatherproofing tape provided.

You are advised to seal the connectors only after you have verified optimal alignment of the antennas using the Link Test as described in the documentation that comes with the Tsunami MP.11. Doing so lets you adjust antenna placement and cable routing without removing the tape.

1.Prepare the cable and connectors so that they are free from dust, dirt and grease.

2.Attach the tip of the weatherproofing tape to the cable just above the connector. Holding the tape in its position, now stretch the tape and wind it half-overlapped around the cable and connectors to form a void-free joint. The degree of stretch may vary in different sections of the joint, as long as the overlaps accomplish a void-free application.

3.To protect the weatherproofing stretch tape from the effects of Ultra-Violet (UV) radiation (for example, from direct sunlight), you should protect the joint with two half-overlapped layers of any vinyl plastic electrical tape. Alternatively, you can apply silicone sealer to protect the weatherproofing tape from sunlight, rain and other weather conditions.

Grounding System

Direct grounding of the antenna mast, Tsunami MP.11a hardware and surge arrestor is very important.

Note: A safety grounding system is necessary to protect your Tsunami MP.11a hardware from lightning strikes and the build-up of static electricity.

WARNING! The antenna mast, Tsunami MP.11a hardware and surge arrestor must be connected to the same ground, using an equi-potential bonding conductor.

A good electrical connection should be made to one or more ground rods, using at least a 10AWG ground wire and non-corrosive hardware. The grounding system must comply with the National Electrical Code and safety standards that apply in your country. Always check with a qualified electrician if you are in doubt whether your Tsunami MP.11a hardware installation is properly grounded or not.
