Wilson omnidirectional (or omni) cellular antennas pull in signal from all directions. Omnidirectional antennas are the most useful for multi-carrier setups and are far easier to install than other outdoor options. They pull in all existing signal in an area.
The Plus line provides higher gain than the regular, giving more overall power to your system.
Be sure to purchase an omnidirectional antenna with the correct ohmage for your system.
