weBoost 311102 (formerly 301102) Glass-Mount Antenna is a multi-band glass-mount antenna that is designed to be used with one of our 50 Ohm amplifiers and features up to 4.8 dB of gain. The Wilson 311102 antenna is omni-directional which allows it to receive signal from all directions. It is attached to vehicle glass such as cars, vans, and SUVs with a 3M adhesive. Therefore, it cannot be easily moved from one vehicle to another. Please note that Glass-Mount antennas are NOT recommended for wireless systems (due to interior-exterior antenna oscillation).
