RG316 Antenna Cable — MMCX to SMA RG316 Adapter
The RG316 antenna cable with interchangeable SMA and MMCX connectors is a practical, lightweight, and reliable solution for connecting external antennas to radio-controlled models, drones, receivers, and other radio equipment. The cable is based on RG316 coaxial cable with 50 Ohm impedance, ensuring stable signal transmission and minimal loss even in challenging operating conditions. Its compactness and low weight make it ideal for installation in confined spaces of models where every gram and millimeter matters.
Connector configurations include SMA (SMA Male or SMA Female) combined with MMCX Male. SMA typically connects to an external antenna, while MMCX Male is suitable for direct connection to a radio module or an antenna connector on a circuit board. This design allows for quick antenna replacement or system reconfiguration without additional housing modifications.
Advantages
- Universal compatibility with a wide range of antennas and radio modules thanks to SMA and MMCX connector options.
- 50 Ohm impedance guarantees optimal line matching and minimal signal loss.
- Multiple length options (5 cm, 8 cm, 10 cm, 30 cm) allow choosing the optimal variant for the drone or device design.
- Low weight (3 g / 5 g / 6 g / 7 g depending on length) reduces structural load and does not affect model balance.
- Easy installation: SMA connects to the antenna, MMCX to the device.

This RG316 adapter is suitable for both professional applications and amateur projects: from upgrading antennas in FPV systems to connecting external antennas to controllers and receivers in various drone models. The choice of length depends on the task: shorter options (5–10 cm) are best for compact installations with minimal weight and balance impact, while a longer cable (30 cm) provides more freedom for antenna placement for better reception in interference conditions.
The cable is easy to bend and install, but it is recommended to avoid excessive twisting and strong tension to maintain electrical parameters and connection durability. Thanks to its low weight (from 3 to 7 g depending on length), it does not alter the flight characteristics of many models and is suitable for use in multicopters, airplanes, and other radio-controlled devices.
By ordering the RG316 antenna cable with SMA and MMCX connectors, you get a versatile and economical component to improve the communication quality of your equipment. Compatibility with various connector configurations allows for quick integration of the cable into an existing system without additional adapters. Manufacturer: China.
