Thunder 8 XB

The Thunder 8 XB is the answer for the operator who is limited to or requires omnidirectional performance that is switchable to "beam" performance at the flip of a switch! The Thunder 8 XB is capable of providing omnidirectional coverage with the added ability to concentrate its signal into a bi-directional beam pattern. Two coax lines run from the switch box (switch box included) to the Thunder 8 XB allowing it to have an omnidirectional or 2 directional beam pattern that is switchable instantly - no rotor required.

The Thunder 8 XB is designed to withstand the harshest environments with trouble-free operation. Omnidirectional performance rivals popular 1/2 wave design and switchable beam pattern provides much higher gain than an omnidirectional with the added benefit of rejection of signals coming from unwanted directions. Like our quad beam antennas, the Thunder 8 XB is engineered on a sturdy aluminum and fiberglass frame.
