WDHP-800-2000

The WDHP-800-2000 is a mission-critical, Wide Band Omni-directional Fully Welded Discone Antenna engineered for high-power transmission and reception across the 800–2000 MHz spectrum. Unlike standard discones that rely on bolted elements, this heavy-duty model features a fully welded 6063T6 aluminum architecture encased in a rugged ABS radome. This design provides absolute mechanical integrity against ice loading and extreme vibration, making it the definitive choice for spectrum monitoring, high-power jamming, and base station applications in arctic, oceanic, and desert environments.

Design: Wideband Versatility & High-Power Denial

The WDHP-800-2000 is engineered for operators who require a single, indestructible aperture to cover the critical cellular, tactical, and L-band microwave frequencies.

• Continuous 500W Power Handling: Most wideband omni antennas fail under the thermal stress of high-power jamming. The fully welded junctions and high-grade materials of the WDHP-800-2000 allow it to sustain 500 Watts of continuous RF energy across the entire band.
• Massive Vertical Beamwidth: With a 78-degree vertical beamwidth, this antenna provides exceptional hemispherical coverage. This makes it ideal for ground-to-air communication and monitoring where the target may be at a high elevation angle relative to the base station.
• Zero Field Tuning: The discone architecture provides an inherently low VSWR (Better than 2:1) across the full 1200 MHz bandwidth. This "plug-and-play" capability is vital for rapid-deployment tactical sites.

Construction: The "Zero-Failure" Architecture

Designed to survive where conventional antennas snap or detune, the WDHP-800-2000 uses a multi-layered protection strategy.

• Fully Welded 6063T6 Aluminum: Every element junction is welded to prevent RF inter-modulation (PIM) and mechanical loosening caused by vibration. This is critical for Oceanic and Arctic applications where wind and ice loading are constant threats.
• ABS Radome & Epoxy Coating: All internal junctions are protected by a high-impact ABS radome, while external metal surfaces receive an epoxy powder coating. This provides a total shield against salt spray, acid rain, sandstorms, and UV radiation.
• Internal Termination: The N-Female termination is housed inside the mounting pipe, ensuring the cable connection is never exposed to the elements, preventing moisture ingress and signal degradation.

Technical Features

• Unified 800–2000 MHz Coverage: Replaces multiple antennas for GSM, LTE, and S-band monitoring.
• Extreme 500W RF Capacity: Optimized for high-intensity Electronic Warfare (EW) and jamming.
• Rugged ABS Enclosure: Protects radiating elements from ice formation and physical impact.
• Omnidirectional 2.15 dBi Gain: Provides a consistent 360° "safety bubble" for convoy or base protection.
• MIL-STD-810G Certified: Tested for extreme shock, vibration, and salt fog survivability.
• Marine-Grade Hardware: All fasteners are Type 316 stainless steel for zero-corrosion longevity.

Integration Guide: Mastering Wideband Omni Coverage

1. Ground-to-Air & Hemispherical Monitoring

Standard collinear antennas have very thin vertical beams, making them poor for communicating with aircraft or drones at high angles.

• The Discone Advantage: The 78-degree vertical beamwidth ensures that whether the signal source is on the horizon or high in the sky, the WDHP-800-2000 maintains a stable link.

2. Tactical Jamming Efficiency

When used in Electronic Countermeasures (ECM), the antenna's ability to handle 500W allows for the creation of a high-intensity "denial zone." Because it is omnidirectional, it provides 360-degree protection for base stations or mobile command centers against a wide range of frequency-hopping threats.

3. Survivability in Saline & Arctic Environments

In coastal or arctic regions, salt crusting and ice buildup can detune an antenna's frequency response. The cylindrical ABS radome prevents ice from anchoring to the elements and keeps salt spray away from sensitive junctions, ensuring the VSWR remains stable year-round.

Strategic EW & SIGINT Guide: WDHP-800-2000 Wideband Mastery

The WDHP-800-2000 is a "zero-failure" tactical asset designed for the 800 MHz to 2.0 GHz spectrum. While high-gain collinear antennas focus energy into a thin "disc" at the horizon, the discone architecture of the WDHP-800-2000 provides a massive 78-degree vertical beamwidth. This makes it the premier choice for Hemispherical Situational Awareness, allowing a single base station to monitor ground-level cellular traffic and high-altitude UAV/Aeronautical data links simultaneously.

1. Mastering Hemispherical Coverage (Ground-to-Air)

In modern tactical environments, threats and signals do not just live on the horizon; they come from high-angle drones (UAVs) and low-orbit satellites.

• The Discone Advantage: Most omni antennas have a narrow vertical beam (often <10 degrees), meaning they "lose" signals as an aircraft flies overhead. The WDHP-800-2000’s 78-degree vertical beamwidth ensures a constant link from the horizon up to near-zenith angles.
• 360° Monitoring: Whether a target is a GSM-900 handset on the street or an L-Band telemetry link 30,000 feet in the air, this antenna maintains a stable 2.15 dBi gain across the entire 360-degree azimuth.

2. High-Power Jamming & Thermal Resilience

To successfully disrupt wideband threats (such as frequency-hopping L-Band data links or cellular triggers), the antenna must handle massive RF stress without "detuning."

• 500W Continuous Denial: The fully welded 6063T6 aluminum construction acts as a superior heat sink. Unlike bolted antennas that develop "hot spots" at loose joints, the WDHP-800-2000 can sustain 500 Watts of continuous jamming power.
• Bubble Protection: This high power handling allows for the creation of a massive "denial bubble," effectively drowning out adversary signals across the entire 800–2000 MHz range, protecting fixed sites or mobile command centers from remote triggers.

3. Survivability in Extreme Arctic & Saline Zones

In the Arctic or at sea, wind-driven ice and salt spray are the primary killers of wideband antennas.

• Ice-Loading Protection: The Cylindrical ABS Radome provides a smooth, tapered surface that prevents ice from anchoring to the radiating elements. This ensures that even in sub-zero "icing" conditions, the antenna's weight remains manageable and its VSWR (2:1) stays stable.
• PIM Suppression: By welding all internal junctions, the antenna eliminates Passive Inter-Modulation (PIM). This is critical for SIGINT, as it prevents the antenna itself from generating "phantom signals" that can interfere with sensitive receiver equipment in high-vibration environments.

4. "Silent" Monitoring: D.C. Grounding & Noise Floor

For sensitive SIGINT operations, the "Noise Floor" is the ultimate enemy. High-speed wind moving across 800-2000 MHz elements creates Precipitation Static (P-Static).

• The Solution: The WDHP-800-2000 is D.C. Grounded. It constantly bleeds off static charge to the mast and earth. This ensures an ultra-low noise floor, allowing a connected receiver to detect low-power "hidden" transmissions or weak frequency-hopping signals that would be buried in the static of an ungrounded antenna.

Tactical Deployment Checklist

• Height vs. Obstruction: Because the discone has a very wide vertical beam, it is sensitive to objects nearby. Mount the antenna at the absolute top of the mast to prevent the mast itself or nearby structures from reflecting the 78-degree signal.
• Cable Integrity at L-Band: At 2000 MHz (2 GHz), cable loss is severe. Do not use standard RG-58. Use LMR-400 or LMR-600. Every 3 dB of cable loss effectively cuts your 500W jamming power or reception sensitivity in half.
• Weather-Proof Termination: The N-Female connection is housed inside the mounting pipe. Ensure the cable is securely tightened and the pipe is sealed to prevent moisture from traveling up the cable jacket, which can detune the 2:1 VSWR.
• Multi-Antenna Spacing: If deploying near other antennas, maintain at least 2 meters of vertical separation. The wide vertical beam of the WDHP-800-2000 can easily "talk" to other antennas on the same mast, potentially desensitizing other receivers.
