An External Antenna is used to support reliable wireless communication by extending signal reception and transmission beyond enclosed structures. It is mounted externally to reduce signal obstruction and support consistent connectivity between onboard electronic devices and remote control, monitoring, or diagnostic equipment. By providing a clear signal path, the antenna helps maintain stable data transfer during equipment operation.Attributes:• Allows antenna placement separate from the client card.• Uses a magnetic base for stable surface attachment.• Simple form allows easy handling and placement.Applications: An External Antenna is installed on the exterior of the equipment to support wireless communication for onboard electronic equipment, enabling stable signal transmission and reception by providing clear external positioning for communication functions.
