## 1. Introduction 

The Taoglas RI.08.A.0121 is an adhesive mount 868MHz road marker/manhole antenna designed for use in conjunction with “Bott’s dots”. The vandal resistant, non-reflective, low-profile housing allows it to be directly mounted onto the pavement, road or manhole. The RI.08 has been designed for the 862-870MHz ISM band and uses the existing road marker style housing created by Taoglas and include a direct mount SMA female connector. 

This antenna can be used in many different applications, such as: 

- Remote Monitoring 

- Smart Metering 

- Security 

When installing this antenna, the SMA female direct mount can be used to directly mount onto a surface, Taoglas can also supply a customized cable with connector to suit a customer’s needs. It is recommended that 3M VHB 4955 Adhesive is used to mount this antenna onto the required surface. 

All cable and connectors are customizable, contact your regional Taoglas sales office for customization and additional support.
