AD-70/A-60120 — Omnidirectional UHF Antenna

Overview

The AD-70/A-60120 is an omnidirectional UHF antenna engineered for horizontal polarization across the 600 to 1200 MHz frequency range. Built with military-grade construction, it supports both continuous monitoring and high-power jamming operations.

Technical Summary

• Frequency Range: 600 to 1200 MHz (UHF)
• Power Handling: Up to 500 W CW
• Polarization: Horizontal (Primary); RHCP (Optional GPS)
• Materials: Hard plastic radome, two-component UV-resistant military green paint (RAL 6014)

Operational Use Cases

• Monitoring of horizontally polarized RF signals
• High-power RF jamming operations
• Integrated GPS location tracking (when optionally configured)

Deployment Environments

This antenna is engineered for rigorous conditions on ground vehicles and fixed sites, featuring MIL-STD-810G compliant environmental ruggedness to ensure durability in tactical environments.

Performance Metrics

• Bandwidth: Wideband UHF coverage (600 - 1200 MHz)
• Maximum Transmit Power: 500 W CW limit
• Environmental Standards: MIL-STD-810G

Setup & Portability

The antenna system is modular, consisting of a radiating element and a selectable base. Available mounting options include a vehicle base, a mast base featuring stainless steel joints, and a plate base designed for through-hole installation.

Compatibility

The vehicle antenna base supports the integration of optional GPS L1 or L1/L2 capabilities. The radiating element mounts to the specific base selected during procurement.

FAQs

• How do transmitter power levels impact antenna selection? Choosing an antenna that tolerates the maximum continuous power output of the transmitter is critical for survival. The AD-70/A-60120 supports up to 500 W CW.
• What determines the radiation coverage of an omnidirectional antenna? Omnidirectional antennas generally provide 360-degree coverage around the azimuth, though elevation beamwidth and gain can compress or shift depending on mounting structures and ground conductivity. Verify specific pattern measurements against the datasheet.
• What limits must be considered when using antennas near transmitters? For receive or monitoring operations near active transmitters, the imparted field strength must remain below the antenna's survival limits. Verify sufficient physical spacing and isolation during site installation.
• Problems we solve: how do we narrow antenna choices? Balancing operating bands, coverage needs and mounting space can make antenna selection difficult. Share those constraints with Cyntony to compare candidate antennas and identify what needs manufacturer confirmation (Our process).
• Outcomes we deliver: what changed for Espy's compact monitoring system? Cyntony helped Espy source antennas that fitted a compact transit case and coordinated later sourcing revisions for removable mounting. This documented result concerns Espy's system; it does not establish this product's dimensions, mounting features or performance (Espy case study).
