The Sirio SA-242 is a mechanical adapter designed for installing mobile antennas with different thread sizes.
Its M6 male lower thread screws into a mount or support with an M6 female thread. The upper section provides an M7 female thread for fitting a radiator or antenna equipped with an M7 male connection.
Its metal construction and chrome-plated finish provide mechanical strength and a suitable appearance for vehicle installations, antenna brackets and compatible radio communication systems.
It offers a straightforward way to reuse an existing antenna mount with a different threaded antenna, avoiding the need to replace the complete installation or coaxial cable.
The adapter is intended for the following configuration:
Before purchasing, verify the diameter, gender and pitch of both the antenna and mount threads. A similar thread diameter does not necessarily guarantee compatibility.
Tighten the adapter securely without applying excessive force that could damage the threads. This accessory provides mechanical adaptation only and does not replace correct antenna tuning or modify the antenna’s electrical characteristics.
