Vehicle exterior antenna

The Wilson 311125 is a 12-inch magnet-mount antenna built for vehicle roofs. It covers 700-2170MHz with up to +6.1 dB gain and terminates in an SMA-Male connector. The omnidirectional pattern receives signals from all directions while moving or parked. It replaces the former 301125 part number and ships from Canada.

50 Ohm booster integration

This antenna connects directly to any 50 Ohm signal booster system supporting LTE, 4G and 3G bands. The magnetic base secures to metal surfaces without drilling and can be removed quickly. Its SMA-Male plug mates with standard booster cables, freeing the installer from proprietary connectors. No additional adapters are required for Wilson amplifiers.

Sustained mobile operation

The omnidirectional element maintains consistent reception across the full 700-2170MHz range during extended drives through varying terrain. Gain remains stable at up to +6.1 dB without the drop-off seen in directional designs when the vehicle changes heading. The rugged housing withstands continuous exposure to weather and vibration. Performance stays reliable for daily commercial or personal use.

Questions about this item

How much gain does the 12-inch antenna deliver across the 700-2170MHz range?

The antenna provides up to +6.1 dB gain over the full 700-2170MHz frequency span.

Will the magnet mount hold securely and stay cool during continuous all-day use on a vehicle roof?

The magnet mount is designed for permanent vehicle exterior attachment and the passive antenna generates no heat during operation.

Which booster impedance and connector type must I already have for this SMA-Male antenna to work?

You need a 50 Ohm signal booster equipped with an SMA-Female port to connect this antenna directly.
