| AG-75 | VHF Low Band Base Station Ground | 66-88MHz | Unity |  |  |  |
The AG-75 is a heavy-duty, military-grade Omnidirectional Ground Plane Antenna specifically designed for the 66–88 MHz VHF low-band. Constructed from high-strength 6063T6 aluminum alloy and finished with a durable epoxy powder coating, this antenna is built to serve as a reliable base station hub for tactical and industrial networks. With a focus on long-range propagation and high-power stability, the AG-75 delivers 2.15 dBi (Unity) gain and handles up to 500 Watts of RF power, ensuring robust signal saturation across a 2.5 MHz bandwidth.
Hardened Construction & Strategic Finish
Industrial-strength materials for persistent theater operations. The AG-75 is fabricated from 6063T6 ultra-corrosion-resistant architectural aluminum alloy, ensuring a high strength-to-weight ratio. The all-metal design prevents the formation of "Signal Cells," effectively eliminating internal inter-modulation—a critical requirement for maintaining signal integrity during high-power broadcasts. The antenna is finished in a military-grade olive green epoxy powder coating, providing a resilient barrier against salt spray, UV radiation, and abrasive sand. All mounting hardware and fasteners are made of marine-grade stainless steel.
Operational Efficiency
True omnidirectional dominance with superior "Null Fill." The antenna provides a consistent 360-degree horizontal radiation pattern with a wide 78-degree vertical beamwidth. This wide elevation aperture ensures excellent "null fill," providing reliable connectivity for nearby mobile units and assets at varying elevations. For maximum longevity, the N-Female termination and feed cable are completely enclosed within the mounting pipe, shielding the critical electrical connections from moisture, ice, and mechanical stress.
