8226 GNSS Surge Suppressor Installation Guide
Part Number 8226-0002-0050, Revision: 8

Introduction

Safran recommends the use of an inline coaxial protector for all products connected to an outside GNSS antenna.
Safran offers the Model 8226 GNSS Antenna Surge Suppressor to protect a connected GNSS receiver from damaging voltages occurring on the antenna coax cable. Voltages exceeding the impulse suppressor trip point are shunted to the system ground. The Model 8226 is designed to withstand multiple surges.

Installation

2.1. Mounting Bracket Installation
Install the suppressor indoors, preferably where the coax enters the building. Connect the largest- gauge grounding wire available to the mounting bracket, using the M8 attachment screw; see Fig. 2: 2.2. Grounding Plate Installation
Optionally, the suppressor can be mounted to a grounding panel or bulkhead, as shown in Fig. 3: Safran offers a Surge Protector Grounding Kit, part number 8226-0002-0600, that serves as a single point ground connection for the Model 8226 Surge Suppressor. The kit includes a copper grounding plate on melamine- covered particle board, mounting hardware, copper strapping, strap clamps, ground wire, a ground clap, copper paste, an appropriate mounting bracket, and ancillary hardware. A single point ground system is recommended to provide optimum protection from lightning strikes.

1. Mount the grounding panel indoors, preferably close to where the antenna coax enters the building and direct access to the system ground is available.

2. The grounding panel must be connected to a low impedance (both low resistance and low inductance) ground system to assure proper operation of the surge protection equipment.
   To minimize the inductance between the ground plate and system ground inter connection, keep the copper grounding strap as straight as possible.

3. Limit bends to a radius of 8 inches or larger. Thoroughly clean the copper panel to remove any oxidation or contaminants prior to installation. Apply the supplied copper paste to all junctions on the copper panel to maintain a low-impedance connection.

Each Model 8226 includes two clamp type male N connectors. These connectors can be used to splice the Model 8226 into the antenna coax. The connectors are compatible with CAL7xxx cable assemblies and Times Microwave LMR- 400 equivalent coax. Connector assembly instructions are shown below: 2.3. Assembly Instructions, Type N Connectors, and Clamps
The instructions below apply to Type N Connectors, part number P051-0001-0100. Using the  manufacturer’s part list, verify that all the connector parts are included. (See also connector diagram below.) 2.4. Cable Assembly Instructions – Clamp

Step 1 Stripping Braid Wire
Strip the braid wire where the connectors will be installed. Strip the cable as shown in illustration on  the right; follow the cable stripping dimensions asrecommended by the connector manufacturer.
Step 2 Nut, Washer, Gasket, and Clamp
Place all the parts in order and make sure the assembly direction is correct.
Step 3 Spreading Braid Wire and Stripping Inner Conductor
Fold the braid wire backward onto the braid clamp and make it spread evenly.
Step 4 Contact Pin Soldering
While soldering the contact pin, it must be soldered carefully, and the pin must remain free of tin-solder.
Step 5 Fastening the Nut
Install metal screw onto nut, and spin into the connector body until hand- tight. Use wrench and tighten the nut.
