High-Performance Dual Polarized Log Periodic Antennas for Military & Intelligence

Antenna Experts solves this with our world-class dual polarized log periodic antenna systems. We provide passive antennas in versatile, compact form factors that deliver extreme wideband performance without compromising on stealth or efficiency. A dual-polarized log-periodic antenna is a highly versatile, directional antenna designed to operate over a very wide range of frequencies while handling two different radio wave polarizations simultaneously.

Broad Frequency Coverage & True High-Gain Design

The LPDP series ensures powerful and consistent performance across an extensive operating frequency range of 20 MHz to 3000 MHz. Because our dual polarized log periodic dipole antenna does not use loading techniques to artificially reduce the overall size of the array, it maintains exceptional signal integrity and true high gain. Furthermore, every military dual polarized LP antenna is rigorously designed to meet strict MIL-STD-810G parameters, guaranteeing rugged durability and reliability in the field.

Optimized for SIGINT, Electronic Warfare, and Surveillance

Our LPDP series is the ultimate tactical solution for mission-critical operations. It is uniquely suited for Signal Intelligence (SIGINT), Electronic Warfare (EW), spectrum monitoring, and RCIED jamming applications. Thanks to its two independent terminations, this antenna is highly capable of simultaneously transmitting and receiving both vertical and horizontal (E & H) polarized signals, making it an indispensable tool for comprehensive spectrum scanning and secure surveillance.

Versatile Circular Polarization Capabilities (LHCP & RHCP)

Beyond simultaneous E and H polarization, our tactical dual polarized LP antennas offer unparalleled field flexibility. By integrating a 90-degree hybrid coupler (not supplied), users can easily generate field-selectable Left Hand Circular Polarized (LHCP) or Right Hand Circular Polarized (RHCP) signals. Connecting the two array terminations directly to the quadrature hybrid’s output delivers power 90 degrees out of phase, instantly converting your array into a highly adaptable, switchable circular polarized system.

Core Technical Specifications of Dual Polarized Log Periodic Antennas

The LPDP series is designed for extreme wideband performance and rugged military use, balancing high power handling with operational versatility. Due to their ability to handle both vertical and horizontal polarized signals simultaneously without being easily detected, these antennas are tailored for defense and intelligence operations: 

Switchable Circular Polarization (LHCP & RHCP)

The LPDP series tactical antennas offer advanced polarization flexibility. By integrating a 90-degree quadrature hybrid coupler (field selectable, not supplied), users can easily generate Left Hand Circular Polarized (LHCP) or Right Hand Circular Polarized (RHCP) signals. When both feed lines are connected to the coupler’s output, the power delivered to each orthogonal array is 90 degrees out of phase, allowing for seamless switching between circular polarizations.

Tactical Compact Models: LPDP-20-80-500 & LPDP-20-3000L

For rapid deployment in the field, Antenna Experts offers the LPDP-20-80-500 (20-500MHz) and LPDP-20-3000L (20-3000 MHz) compact military tactical LPDA antennas.

• Compact Design: These specific models utilize advanced loading techniques to reduce the overall size of the cross-element array, making them perfect for high-power transmission or mobile spectrum monitoring.
• Rapid Assembly: Features a specially designed mounting arrangement that allows for complete assembly in under 10 minutes. Dual polarized log periodic antenna above 300MHz is supplied completely sealed in fiberglass radome/housing to protect the antenna from severe environmental conditions.
• Environmental Protection: Finished with a heavy-duty powder coating to withstand the most severe environmental conditions. All the mounting hardware supplied with dual polarized log periodic antenna is made of high-grade stainless-steel materials.
• Log-Periodic Design: A log-periodic dipole array consists of multiple dipole elements of varying lengths. The lengths and spacing of these elements increase logarithmically from the front (pointing toward the signal) to the back. This unique geometry allows the antenna to maintain a consistent radiation pattern and impedance across a massive bandwidth (from 400 MHz up to 6 GHz).
• Dual Polarization: Standard antennas usually handle one polarization (either vertical or horizontal). A dual-polarized antenna actually contains two sets of log-periodic arrays mounted on the same boom, typically offset by 90 degrees (either Horizontal/Vertical or +45°/-45° slant). This allows it to transmit or receive two orthogonal signals at the exact same time.
• Ultra-Wideband Performance: Antenna Experts MIL-STD dual polarized log periodic antenna can replace multiple single-band antennas, save space and reducing installation complexity which provides strong and consistent performance from 20 MHz to 3000 MHz.
• Simultaneous Polarization:  Because dual polarized log periodic antenna can handle two independent data streams via dual polarization, they are highly effective for 4G LTE, 5G, and Wi-Fi MIMO networks, significantly boosting data speeds and reliability. Capable of receiving and transmitting both vertical and horizontal (E & H) polarized signals simultaneously via two independent terminations.
• Polarization Diversity: Radio signals often reflect off buildings or terrain, changing their polarization. A dual-polarized log periodic antenna can capture the signal regardless of its orientation, mitigating "signal fading" and ensuring a stable connection.
• High Directional Gain: They focus RF energy in a specific direction, providing high gain and rejecting interference from behind or the sides. Operates at D.C. ground with a low-resistance discharge path, ensuring excellent lightning protection and high immunity to noise.
• Standard LPDP Series: Achieves high gain across the 20 MHz to 3000 MHz range without using size-reducing loading techniques. This maximizes overall array performance. Our standard arrays achieve their broad frequency range and high gain without the use of loading techniques, maximizing overall efficiency.

Standard vs. Compact Models of Dual Polarized Log Periodic Antennas

• Compact Models (LPDP-20-80-500 & LPDP-20-3000L): Specifically designed for rapid tactical deployment (assembly under 10 minutes). To achieve their smaller footprint, these specific models do utilize loading techniques. They are powder-coated for severe environments and are particularly suited for lower-power transmission or mobile spectrum monitoring.

Why Armed Forces Choose Antenna Experts Dual Polarized Log Periodic Antenna?

If you are looking at Antenna Experts for a Dual Polarized Log Periodic Antenna (LPDP series), you are stepping into the realm of high-end, military-grade RF equipment. Our LPDP series antennas are not standard commercial Wi-Fi or cellular antennas; they are built for demanding applications like Signal Intelligence (SIGINT), Electronic Warfare (EW), RCIED jamming, and critical spectrum monitoring.

1. Military-Grade Build Quality (MIL-STD-810G) 

• Premium Materials: Our dual polarized log periodic antenna use 6063T6 ultra-corrosion-resistant architectural anodized aluminum alloy for the elements and booms. All nuts, bolts, and hardware are type-316 marine-grade stainless steel.
• Weatherproofing: Dual polarized log periodic antennas are finished with a protective powder coating (often olive green for tactical use) to defend against corrosive gases, salt spray, acid rain, and desert sandstorms. Many models operating above 300 MHz also come with specialized fiberglass radomes to prevent ice formation.

2. True Wideband Performance Without Compromise 

Many compact wideband antennas use a "passive loading technique" to artificially shrink the size of the antenna array. While this saves space, it sacrifices gain and efficiency. Antenna Experts boasts that their primary high-gain LPDP models do not use loading techniques. This ensures you get high efficiency, low VSWR (Voltage Standing Wave Ratio), and a strong, high-gain signal across the entire stated frequency band (with models covering anywhere from 20 MHz up to 3000 MHz).

3. Advanced Polarization Flexibility of Dual Pol LPDA

The LPDP series is highly versatile in how it handles signal polarization:

• Simultaneous V/H: Dual polarized log periodic antenna receive and transmit both Vertical (E) and Horizontal (H) polarized signals at the exact same time. Capable of receiving and transmitting both vertical and horizontal (E & H) polarized signals simultaneously via two independent terminations.
• Circular Polarization Ready: By attaching a 90-degree quadrature hybrid coupler (field selectable), you can force the two orthogonal arrays to operate 90 degrees out of phase. This allows the antenna to generate Left-Hand Circular Polarized (LHCP) or Right-Hand Circular Polarized (RHCP) signals, making it excellent for satellite tracking and complex surveillance.

4. Lightning Protection and Noise Immunity 

In outdoor and tactical deployments, static buildup and lightning are major risks. Antenna Experts’ log periodic antennas operate at a D.C. ground. This provides a low-resistance discharge path that protects connected receivers from lightning strikes and significantly reduces static noise, ensuring cleaner signal monitoring.

5. Rapid Tactical Deployment 

Despite their robust build, these antennas are designed for quick mobility.

• Fast Assembly: The tactical variants feature folding or removable elements with fast-deployment self-locking devices. Two operators with simple hand tools can fully assemble even the larger arrays in less than 10 minutes.
• Easy Shipping: Because the elements break down into smaller segments, the antennas can pack down tightly for easy transportation to remote sites.
