These tactical log periodic antennas are highly suitable for mission-critical applications, including surveillance, signal intelligence (SIGINT), and electronic warfare (EW). Their low VSWR and high-efficiency design make them the ideal choice for continuous receiving, transmitting, scanning, monitoring, and jamming operations.

Rugged Durability and Weatherproofing

Built to survive the most extreme environmental conditions, our antennas feature a robust mechanical design engineered for longevity. Models operating above 400MHz are equipped with a heavy-duty fiberglass radome, ensuring years of maintenance-free life. To make the system completely weatherproof, the coaxial cable is securely sealed inside the support boom. The entire antenna is finished with an epoxy-based powder coating, providing absolute protection against corrosive gases, UV radiation, acid rain, desert sandstorms, and saline coastal environments.

Compact, Portable HF VHF Solutions

Our HF VHF log periodic antenna series is designed with logistics and rapid deployment in mind. Utilizing advanced loading techniques to reduce the overall size of the array, these antennas feature removable elements that are supplied in two modular segments. Attached via heavy-duty stainless steel nuts and bolts along the boom, this design makes our antennas incredibly easy to ship, transport, and handle in the field without sacrificing heavy-duty performance.

Tactical Log Periodic Dipole Antennas: Unyielding Performance for Armed Forces

When mission success depends on uninterrupted, secure communication and signal intelligence, compromise is not an option. Antenna Experts designs and manufactures ultra-reliable Log Periodic Dipole Antennas (LPDAs) engineered specifically for the rigorous demands of global defense forces. Built for Electronic Warfare (EW), COMINT, ELINT, and critical tactical communications, our broadband arrays deliver continuous, high-gain performance in the world’s most unforgiving environments.

Why Defense Forces Choose Antenna Experts Log Periodic Dipole Antenna?

Armed forces rely on Antenna Experts Log Periodic Dipole Antennas because they deliver uninterrupted, wideband performance in a highly survivable, tactical form factor. They are specifically engineered to handle the rigorous demands of military communications, signal intelligence (SIGINT), and electronic warfare (EW).

1. Uncompromised Broadband Performance

Unlike many compact tactical antennas that sacrifice efficiency for size, these LPDAs achieve massive frequency coverage—spanning from as low as 10 MHz up to 6000 MHz depending on the specific model—without relying on artificial loading techniques. This true log-periodic design ensures continuous high gain, low VSWR, and strong, reliable performance across the entire operational band without dead zones.

2. Extreme Environmental Survivability

Military environments are unforgiving, requiring hardware that will not degrade in the field. The antennas are manufactured using 6063T6 ultra-corrosion-resistant anodized aluminum alloy and 316 marine-grade stainless steel hardware. The exterior is treated with a heavy-duty, epoxy-based powder coating—typically in a military olive green with a matte finish—to provide complete protection against corrosive gases, UV radiation, coastal salt spray, and desert sandstorms. Additionally, the coaxial cables are fully sealed inside the support booms to keep the system entirely weatherproof.

3. Rapid Tactical Deployment

Speed is a critical factor for mobile units. These arrays are designed with segmented support booms and foldable or removable elements. A team of two technicians can assemble and deploy the system in under 10 minutes using simple hand tools. When broken down, the compact shipping length (often around 6 feet for tactical models) makes them highly mobile and easy to transport.

4. Electronic Warfare & High Power Handling

Because of their broadband stability and high power-handling capacity (often 500W to 2000W), these antennas are exceptionally versatile. Armed forces utilize them not just for standard transmission and reception, but for continuous scanning, communication intelligence (COMINT), electronic intelligence (ELINT), and active jamming applications where maintaining a powerful, uninterrupted signal is vital.

5. Battle-Ready Survivability 

Military hardware must withstand extreme conditions. Our LPDAs are constructed from 6063T6 ultra-corrosion-resistant anodized aluminum alloy and marine-grade stainless steel. Coated in a heavy-duty, epoxy-based military olive green matte finish, the array minimizes visual signature while providing absolute protection against UV radiation, coastal salt spray, and desert abrasions. All coaxial cables are fully sealed within the support booms for comprehensive weatherproofing.

6. Lightning and Noise Immunity

To protect expensive transceivers and sensitive monitoring equipment in austere environments, the complete array operates at D.C. ground. This provides a low-resistance discharge path, safely grounding the system against direct lightning strikes while simultaneously offering high immunity to background static and electrical noise.
