The TFX257 has been expertly engineered by Taoglas with innovation in mind, the design is based on our excellent design history in pioneering flexible PCB antenna technology. TFX257 is supplied with pre adhered adhesive for ease of installation and has an enclosed carrier terminated with a FAKRA connector. The transparent flexible antennas are an alternative to standard Flexible PCB antennas where the user may want to install an antenna in a covert area or on a surface, they may want to keep visible. The performance of the antenna is based on the environment where it is placed, care should be taken to mount at least 20mm from metal components where possible. Typical Applications Include: - Automotive and Commercial Transportation - EV Charging and Parking Bays - Digital Signage and Display screens - Point Of Sale Kiosks The installation of the Taoglas Invisible Antenna™ series follows a similar installation method to flexible PCB antennas, as detailed in this application note. As installing a transparent material may show obvious flaws/debris, take care to wipe the area clean before adhering the antenna. The flexible antenna can be disconnected from the body to make installation easier. Where support may be an issue, we would advise using a double-sided adhesive on the housing to ensure the housing body installation does not add any additional pull force to the antenna as this will affect the antennas performance and the adhesive’s performance. The feed is not designed to be load bearing and loads of over 0.5Kg can break or damage the feed resulting in the antenna disconnecting. The TFX257 is connected via a FAKRA Code I male connector for ease of installation. If a custom connector is required please contact your regional Taoglas customer support team. 2 www.taoglas.com SPE-22-8-163-A |**Electrical**|**Electrical**|**Electrical**|**Electrical**|**Electrical**|**Electrical**|**Electrical**|**Electrical**|**Electrical**| |---|---|---|---|---|---|---|---|---| |**Band**|**Frequency**
