Product description

The Wilson 301143 and 301149 Dual Band Ultra-Slim Antennas are dual band direct-connect antennas with 3/2 dB of gain. They are designed to be used as the internal antenna on one of the vehicle amplifiers. The antenna is made of plastic-coated steel wire. This antenna is multi-band, and covers all global voice and 3G networks. The antenna comes with 7.5 ft of RG174 coaxial cable, with either an FME female or SMA Male connector.


The Wilson ultra-slim antennas are omni-directional antennas. Omni-directional antennas broadcast signal from all directions, and so should be situated in the center of the area where you wish to improve signal.

Mounting details

The Wilson 301143 and 301149 can mount to any non-metal surface with 3M adhesive mount. The standard installation for this antenna is to attach it to the right hand side of the drivers seat, providing a cell zone of coverage throughout the vehicle.
