Need help?Do you have a question about the SSI AVIOR and is the answer not in the manual?
This document provides a Quick Installation Guide for the Avior™ antenna, specifically item number HAN25010-1-M, designed for use in rugged and harsh roadside environments, including severe weather conditions and extreme temperatures. The guide outlines the necessary steps for proper installation and emphasizes the importance of weatherproofing to ensure optimal performance and longevity of the device.
The installation process begins with an introduction to the Avior™ antenna, providing a visual representation of its front and back, along with key dimensions. This initial overview helps installers familiarize themselves with the physical characteristics of the antenna before proceeding with the mounting steps.
The primary method for mounting the Avior™ antenna is through U-Bolt installation. The guide details the recommended pole dimensions for this method, specifying a minimum width of 25mm and a maximum width of 50mm. Clear diagrams illustrate how the U-Bolts and U-Bolt Bracket should be assembled and attached to a pole, ensuring a secure fit. This section is crucial for establishing the physical stability of the antenna in its operational environment.
Beyond the primary mounting, the guide strongly recommends the installation of a steel safety wire. This safety feature is designed to provide an additional layer of security, preventing the antenna from falling in case the primary mounting fails. The instructions show how the safety wire should be attached securely to both the antenna, using its pre-drilled holes, and the gantry or mounting structure. This step underscores the importance of safety in outdoor installations, particularly for equipment exposed to environmental stressors.
A significant portion of the guide is dedicated to weatherproof outdoor installation, highlighting its critical importance for the Avior™ antenna's performance and durability. The document references the Certified Wireless Network Administrator (CWNA) Study Guide, emphasizing that "Water damage is often a serious problem with cabling and connectors." Therefore, the guide stresses the need to weatherproof cables and connectors and secure them against movement. Industry best practices, such as using drip loops and coax seals, are recommended to prevent water seepage and damage.
Three specific methods for weatherproofing antenna and cable connectors are introduced: making drip loops on cables, protecting connectors using cold shrink tubes, and protecting connectors using a combination of electrical tape and butyl rubber. Users and installers are encouraged to review and evaluate these techniques to ensure a successful and robust installation.
The first weatherproofing method, "Cable Drip Loop," involves creating a small "U" shape in the cable before it connects to the antenna or reader. This loop is positioned lower than the connector, allowing water to flow along the cable and drip away, thereby preventing it from ingressing into the connector. This simple yet effective technique is vital for diverting water away from sensitive connection points.
The second method, "Cold Shrink Tube," offers a fast and easy way to weatherproof cable connections. A cold shrink tube, typically an open-ended rubber sleeve with a plastic core, is placed over the cable and connector. The plastic core is then pulled off, causing the rubber sleeve to shrink tightly around the connection, providing a secure and weatherproof seal. This method also helps stabilize the cable connection against wind and vibration. The guide lists the necessary tools, including a torque wrench for proper connector tightening and the cold shrink tube itself. Detailed procedures are provided, starting with running the coax cable through the tube, connecting and tightening the cable connector to the antenna with a torque wrench to ensure correct internal seals, and finally aligning the cold shrink tube and pulling its rip cord to seal the connection.
The third weatherproofing method involves "Tape and Butyl Rubber," a widely adopted practice for outdoor cable connection weatherproofing. This technique often utilizes weatherproofing kits containing electric, vinyl, or plastic tape in combination with butyl rubber or mastic wrap. The guide outlines the tools required: a torque wrench, electric/vinyl/plastic tape, and butyl rubber/mastic wrap. The procedure begins with connecting and properly tightening the cable connector to the antenna using a torque wrench. Next, 3/4" (19mm) electric, vinyl, or plastic tape is wrapped around the connection, starting about 1" (25mm) from the connector on the cable side, overlapping at half-width, and extending to the antenna connector base. Following this, a piece of butyl rubber, large enough to wrap completely around the connector and extend past the first layer of tape, is stretched and pressed firmly against the connection and cable, ensuring no gaps. Finally, multiple layers (four are recommended) of electric, vinyl, or plastic tape are applied, starting below the rubber and overlapping at half-width, wrapping up towards the antenna connector base. Each subsequent layer should start 1" (25mm) below the previous one. After completing all layers, installers are instructed to check for any areas where water could collect and smooth them out.
Overall, the Avior™ antenna is designed for robust performance in challenging outdoor conditions, and this quick installation guide provides comprehensive instructions for its secure mounting and essential weatherproofing. The emphasis on proper installation techniques, including safety wire and multiple weatherproofing methods, ensures the antenna's reliability and longevity in smart city applications such as electronic tolling, electronic vehicle registration, fleet management, parking, and secure access control. The guide reflects SSI's commitment to providing innovative products and ensuring customer success through detailed technical support and best practices.
