RFID antenna selection
A narrow-band rubber antenna with TNC male termination
GL491-TNC is the TNC male version of the GL491 rubber RFID antenna. The original sheet names 902–915 MHz operation, so confirm that the reader or terminal uses this exact band before choosing it.
The antenna has 3 dBi listed gain, 50 Ω impedance and linear polarization. Its Ø15 × 200 mm ABS body is installed by a screw connection; the source does not specify a cable.
Check the mating TNC female port and physical clearance around the 200 mm body. Do not assume compatibility with nearby 868 MHz or the full 902–928 MHz band from this document.
Send the required band, connector, installation limits and quantity. We will review the request against the selected model.Request a Quote→
Compare product configurations
Compare the exact model and its published specifications before requesting a sample or production quote. A connector or cable change must be confirmed for the selected model.
Values below are copied from the individual product records. Where a unit or value is not stated, consult the model datasheet before specifying the part.
Before ordering
Match every required operating band, rather than relying only on a product-family name.
Check connector gender, cable route, mounting space and the interface on your device.
Use the exact model datasheet to confirm the test conditions and installation limits.
Select a standard model or discuss a change
For a standard configuration, send the model number and expected quantity. For a change, include the required band, enclosure space, cable length and connector. Sample availability, minimum order quantity and delivery are confirmed with the quotation.
Which specifications should I confirm for this model?
Use the listed frequency, connector and mounting information together. Compare the values with your radio interface and available installation space; do not substitute parameters from a similar-looking model.
Can I change the cable or connector?
Describe the cable length, connector type and installation constraints in your enquiry. A change is subject to review for this exact model; the published configuration is the reference until a revised specification is confirmed.
What should I send for a sample or production quote?
Include the model, expected quantity, delivery destination and any drawing or interface requirement. Ask for confirmation of the sample configuration, lead time and production terms before placing an order.
Discuss your antenna requirements
Send the model, operating band and installation requirements. We will review the configuration and confirm pricing, samples and delivery for your project.
