SMA male to male Cables for Antennas
The SMA connector
The SubMiniature type A or SMA connector is a sub-miniature threaded radio frequency connector that is used in a wide variety of wireless networking applications. It's compact, easy to handle and mates securely for a connection that jolts or vibrations cannot disturb. SMA connectors are also versatile, with right-angle geometry SMA connectors for creating connections that are even more compact and robust. This 50 Ohm connector supports microwave frequencies up to 18 GHz with minimal signal loss and exemplary power handling.
SMA male to SMA male cables
Double male SMA cables carry two male SMA connectors.
The male SMA connector has a cylindrical body, internalized threads, and an inner conductor pin. The male connector mates with a female SMA connector by screw-coupling. You can tighten the mated connection via the hex nut on the male connector body.
This pre-assembled male-male SMA extension cable uses high-quality, flexible, low-loss coaxial cable for reliable performance. Here are the key coaxial cable types for male-to-male SMA antenna cables:
LMR 100 cable is a semi-rigid, 50-Ohm coaxial cable that is renowned for its superior performance and ultra-low signal loss. Its low attenuation rate is because of the double shielding of the coax with braided and foil layers. LMR 100 has a diameter of 0.11 inches or (2.79mm) and is also highly flexible, with a bend radius of 0.25 inches (6.24mm).
LMR 100 cable is another semi-rigid, low-loss cable with an overall diameter of 0.195 inches (4.95mm), larger in diameter than LMR 100. It is also double shielded and its flexible PVC jacket makes it suitable for outdoor use.
- RG 174
This coaxial cable has an identical diameter to LMR 100 but only has a single layer of shielding and greater attenuation. LMR 100 is the superior choice.
SMA male to SMA male cable applications
The SMA connector is a key connector type for cellular networking, GPS, LoRa, testing and measurement, and Ham radio. They are found on antennas, within radio devices and mounted on PCBs.
Use SMA cables as:
- Extension cables
Male to male SMA connectors can create a reliable electrical and mechanical communication between radio devices and components that carry an external SMA female connector. Use this cable with LNAs and GPS radios or cellular signal boosters.
SMA antennas often carry female connectors because they carry a receptacle rather than a pin and are less easily damaged. They require a male connector cable to connect to radio devices that also carry a female SMA connector. Use these SMA male extension cables to run a cable from indoor to outdoor settings. Low-loss cable is essential for applications that have weaker signals like GPS. If wall-mounting antennas, you can use this cable with an SMA L-mount.
