Purchasing questions
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.
