Add an externally mounted antenna to compatible cellular equipment operating at 800/1900 MHz. The Wilson Electronics 311128 combines an omnidirectional antenna element, a magnetic mount and an attached 12.5 ft RG174 cable. Its cable ends in a TNC male connector, so the receiving equipment must provide a compatible TNC antenna connection. The magnetic base allows the antenna to be placed on an appropriate ferrous-metal surface without permanent hardware. This mounting approach is useful where an antenna position may need to be changed during installation or where drilling is not preferred. The attached cable provides a fixed run between the antenna location and the connected cellular device or signal system. An omnidirectional pattern receives signal around the antenna rather than concentrating reception in one fixed direction. That distinguishes this configuration from directional antennas that must be aimed toward a known signal source. This specific antenna configuration combines 800/1900 MHz operation with a magnetic mounting method, 12.5 ft of RG174 cable and a TNC male termination. Confirm the receiving equipment supports the required frequency bands and connector type before installation.
