| AG-150 | VHF High Band Ground Plane Antenna | 136-174MHz | Unity |  |  |  |
The AG-150 is a professional-grade Omnidirectional Ground Plane Antenna engineered for the 136–174 MHz VHF high-band. Constructed from high-quality brass and finished with a specialized epoxy-based powder coating, this rugged all-weather model is designed for elite base station performance. With a focus on signal purity and structural durability, the AG-150 provides a stable 2.15 dBi (Unity) gain and high 500-Watt power handling capacity, making it a primary choice for military and industrial VHF networks.
Hardened Construction & Strategic Finish
Enhanced protection for mission-critical reliability in harsh theaters. The AG-150 features an all-brass radiating architecture, which is fundamental for preventing "Signal Cells." This design choice eliminates internal inter-modulation (IM) and ensures signal fidelity during high-power operations. To withstand severe environmental conditions, the antenna is finished in a military-grade olive green epoxy powder coating. All mounting hardware and fasteners are fabricated from marine-grade stainless steel, ensuring total corrosion immunity.
Operational Efficiency
True omnidirectional dominance with superior "Null Fill." The antenna delivers consistent 360-degree coverage with a wide 78-degree vertical beamwidth. This exceptionally wide elevation aperture provides excellent "null fill," ensuring the localized area is saturated with signal and effectively eliminating communication "dead zones" common with narrower-beam antennas. For maximum field survivability, the N-Female termination and feed cable are completely enclosed within the mounting pipe, shielding the critical RF connections from moisture, ice, and mechanical strain.
Detailed Technical Features
- VHF High-Band Mastery: Optimized for the 136–174 MHz spectrum, ideal for tactical voice and data links.
- All-Brass Radiator: High-quality brass core offers superior electrical conductivity and mechanical stability for high-power operation.
- Massive Power Handling: Facilitates up to 500 Watts of continuous RF power, supporting robust tactical broadcasting and electronic attack.
- Inter-Modulation Suppression: Specialized design prevents "Signal Cells," maintaining a clean RF environment for co-located receivers.
- High-Angle Connectivity: A 78° vertical beamwidth maintains signal integrity for ground-level units and assets at varying elevations.
- Weather-Shielded Feed: Internalized cable routing through the support pipe provides 100% protection for the N-Female connector.
- Zero Field Tuning: Factory-calibrated for an elite VSWR of better than 1.5:1 over the specified bandwidth.
- Quality Assurance: Every antenna is supplied with an individual VSWR test report to guarantee performance out of the box.
Environmental Specifications (MIL-STD-810G Hardened)
The AG-150 is built to perform in the world's most demanding mission parameters:
- Operating Temperature: Certified for mission-critical use from -30°C to +70°C.
- Storage Resilience: Can be safely stored in temperatures ranging from -40°C to +80°C.
- Humidity Defense: Fully functional in 0 to 95% Relative Humidity, designed for tropical and coastal theaters.
- High Wind Stability: Aerodynamically optimized to survive constant winds up to 200 Km/Hr.
Key Advantages, Benefits & Applications
Key Advantages:
- Signal Purity: Brass architecture prevents the non-linear "diode effect" at junctions, ensuring absolute signal fidelity at high power.
- Tactical Logistics: Ground radials are removable, reducing the shipping length to only 0.55 meters for ease of transport.
- MIL-STD Resilience: Complies with MIL-STD-810G standards, making it ideal for high-vibration military environments.
Key Applications:
- Tactical VHF Base Stations: Primary communications link for field headquarters and remote outposts.
- Military & Emergency Services: Reliable wide-area coverage for coordination in rugged or urban terrain.
- Fixed Infrastructure: Ideal for utility sites, refineries, and government installations requiring 360-degree coverage.
- VHF Signal Intercept: Serving as a reliable monitoring probe for SIGINT and regulatory scanning.
Design Features: AG-150 Ground Plane Antenna is rugged all weather model, uses high class chrome plated Brass and does not require any field tuning. The ground plane antenna when packed comes with ground radials removed from the antenna body for ease of packing and transportation.
