AD-18/G-50600 — Mobile Wideband UHF/SHF Antenna

Overview

The AD-18/G-50600 is a wideband UHF/SHF center-fed dipole antenna engineered for heavy-duty ground vehicle applications. Operating continuously from 500 to 6000 MHz, it consists of a radiating element protected by a plastic radome and permanently attached to a standard NATO aluminum mounting flange.

Technical Summary

• Frequency Range: 500 to 6000 MHz (UHF/SHF)
• Impedance: 50 ohms
• VSWR: < 3.0
• Gain: 0 dBi (typical)
• Polarization: Vertical
• Power Handling: 500 W CW at 500 MHz to 150 W CW at 6000 MHz
• Connector: N-Type Female

Operational Use Cases

This wideband antenna supports tactical communication, signal jamming, and spectrum monitoring applications requiring uninterrupted coverage from the UHF band up into the C band.

Deployment Environments

Designed for heavy-duty mobile environments, the antenna is commonly deployed on ground vehicles. Its internal elements are sealed within a rugged plastic radome to withstand harsh external conditions.

Performance Metrics

The antenna maintains a VSWR of under 3.0 and delivers a typical gain of 0 dBi across its full frequency range. It supports high continuous wave (CW) power, handling up to 500 W at 500 MHz and scaling to 150 W at 6000 MHz.

Setup & Portability

The aluminum base flange features four mounting holes equally spaced on a NATO-standard 4.5-inch (114.3 mm) circle for secure vehicle integration. Alternative base plate dimensions are available upon request to accommodate specialized mounts.

Compatibility

Compatible with standard 50-ohm RF systems utilizing an N-Type Female connector and platforms equipped for NATO standard 4.5-inch bolt patterns.

FAQs

• What factors are critical when selecting an antenna for wideband transceiving? Choose an antenna that matches the expected operating frequencies and maximum continuous power output. Providing a well-matched impedance keeps reflected power below levels that can damage the transmitter.
• What does typical gain mean for a dipole omnidirectional antenna? Standard-dimension dipoles typically provide about 0 to 2 dBi of gain within 20 degrees above and below the horizon. Wideband omnidirectional antennas may experience varying gain across their full frequency sweep.
• How is this antenna mounted to a vehicle? It uses an aluminum base flange with four mounting holes equally spaced on a NATO-standard 4.5-inch (114.3 mm) circle. Verify compatibility with your vehicle's bracket or request custom base plate dimensions if needed.
• 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).

Video Notes

A 360-degree product spin highlighting the NATO base flange, the N-type connector location, and the robust radome would be beneficial. A short demonstration of bolting the flange to a standard vehicle bracket could help users visualize installation.
