Frequently Asked Questions
How does a shark-fin combination antenna differ from separate antennas?
A shark-fin combination antenna can combine communications, positioning and timing functions at one compact mounting location, reducing separate roof locations and feeder routing. Confirm the exact signal combination against project requirements.
What information is needed before selecting a rail antenna?
Confirm the required communications, positioning or timing function, mounting position, feeder length, connected equipment, roof sealing conditions and service method before selecting the antenna structure and connector type.
Why are sealing and cable routing important for roof-mounted antennas?
Roof locations remain exposed to weather, vibration and airflow. Confirming mounting-surface sealing, feeder fixation and entry points reduces the risk of water ingress, cable wear and difficult maintenance.
