Overview
The AD-18/G-50300 is a wideband UHF center-fed dipole antenna designed for heavy-duty mobile applications. Covering 500 to 3000 MHz, it features a rugged epoxy composite-enclosed radiating element and an integrated shock-absorbing spring. An optional built-in GPS L1 antenna is available to provide dual-functionality within a single mounting footprint.
Technical Summary
- Frequency Range: 500 to 3000 MHz
- Antenna Type: Center-fed dipole
- Polarization: Vertical (Primary), RHCP (Optional GPS)
- Power Handling: 500 W at 450 MHz; 200 W at 3000 MHz
- Materials: Epoxy composite enclosure, aluminum/plastic base, stainless steel spring
- Coating: Black polyurethane two-component UV-resistant paint
Operational Use Cases
Ideal for tactical communications requiring reliable wideband coverage. The robust design supports heavy-duty ground vehicle integration where maintaining signal integrity during continuous movement is critical.
Deployment Environments
Engineered for harsh outdoor environments and extreme mobility. The built-in stainless steel spring provides superior mechanical stability to absorb shocks and vibrations typical in rugged terrain.
Performance Metrics
- Maximum Power: Up to 500 W CW (frequency dependent)
- Gain: 1 to 2.5 dBi
- Band Coverage: Upper UHF, L-Band, and lower S-Band
Setup & Portability
The antenna base features a standard 4.5-inch (114.3 mm) bolt circle with four mounting holes, simplifying integration onto existing vehicle platforms.
Compatibility
Fully complies with NATO standard mounting interfaces for vehicular antennas.
FAQs
How should I verify power handling for wideband transmission?
Verify the maximum continuous power the transmitter outputs against the antenna's datasheet at your specific operating frequency. Power handling capacity generally decreases as the frequency increases.
Does a dipole antenna require a highly conductive ground plane?
No. Unlike a monopole antenna that relies on a ground plane to form its radiation pattern, a dipole does not depend on ground conductivity to establish its baseline performance.
What is AD-18/G-50300 — Wideband UHF Mobile Dipole Antenna used for?
AD-18/G-50300 — Wideband UHF Mobile Dipole Antenna is categorized as Omni Antenna. Listed applications include Tactical Communication.
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 did Cyntony's tactical-link field test establish?
Cyntony's 2025 XTND-DIRECT field test showed how terrain, antenna height and clearance affected a specific mesh-radio link. The result informs deployment questions; it does not establish range, throughput or suitability for this product (Field-test account).
