Horizon 2.4 Reduces Site Costs

Outdoor case design. Eliminate the enclosure costs required for other radios with our new NEMA 4 case design and weatherproofing kit. The Horizon 2.4 can be indoor or outdoor pole mounted, providing a critical indoor industrial or outdoor wireless access point in the harshest environments.
Eliminates costly RF feed lines. Direct pole mounting means feedline cost and high signal losses are no longer an issue.
Lower installation costs. You can save installation time and expense with our simple pole mounting.
