The Wilson 311101 (formerly known as the 308401 & 301101) is a dual band antenna with 5.12 / 6.12 dB of gain. The antenna is made of stainless steel and is fully weather-proof.
It comes with 10.5 ft. of RG-58 Cable and has an SMA Male Connector.
The Wilson 311101 is an omni-directional antenna. Omni-directional antennas receive signal from all directions, and so the antenna needs to be installed in a vertical position in the area of strongest signal.
The Wilson 311101 includes a standard CB 3/8 inch x 24 thread, 3-way mount mount (901104). The 3-way mount allows the antenna to be connected to a horizontal bar up to 1/2" thick, which is perfect for attachment to a building roof or a truck side mirror.
