Magnetic foot with SMA-female connector
This loose base is equipped with a magnet for mounting. The SMA-female connector is processed in this foot so that you can place a stubby antenna including the 1.5 meter cable with SMA-Male connector.
By removing a stubby antenna from a device and placing it on this base, you can often place it in a much more favorable position for better reception. Ideal if you have a modem or router in a metal cabinet, you can then remove the standard SMA antenna and screw it to this base. The base is a passive product so you can use it for all applications and it is not only suitable for a certain frequency. (At frequencies above 3 GHz there will be more loss).
