High Gain TETRA Antennas

Global Leader in High-Performance TETRA Antennas

With over 30 years of manufacturing excellence, Antenna Experts is a globally recognized TETRA antenna manufacturer and trusted OEM partner. We have proudly exported our premium-quality TETRA communication solutions to over 60 countries and territories worldwide. Driven by decades of continuous development in TETRA technology, we specialize in designing the industry’s highest power-rated antennas. Whether you need a robust solution for a trunked radio network or multi-carrier transmission, our high-performance antennas guarantee maximum reliability in the most demanding communication environments.

TETRA band antenna is a specialized communication device designed to transmit and receive radio frequency (RF) signals within the specific frequency bands allocated for TETRA networks. TETRA is a global standard for digital trunked radio, heavily relied upon by mission-critical organizations like emergency services (police, fire, ambulance), public transport, military, and utility companies because of its high reliability, security, and rapid call setup.

High-Gain Fiberglass Collinear TETRA Antennas

Our 12dB+ gain fiberglass collinear TETRA antennas are engineered for superior omnidirectional coverage. Available in 3dBd, 6dBd, 9dBd, and 12dBd gain options, these antennas utilize multiple vertically stacked, in-phase radiating elements to maximize signal reach. We also offer broadband versions covering the full 380-512 MHz frequency range. Built for extreme weather, the 45 mm exceptionally stiff fiberglass radome restricts tip deflection to just 3 degrees even at wind velocities up to 200 km/hr. For logistical convenience, our 12dBi models are supplied in two sections, making them perfectly suited for air-worthy international shipping via carriers like FedEx, DHL, and UPS.

TETRA Stacked Dipole Arrays for Low Interference

Network clarity is critical, which is why our TETRA stacked dipole antennas are meticulously designed to minimize low passive inter-modulation (IMP) products. By significantly reducing network interference, these low IMP-rated models provide a consistently lower noise floor over the antenna's lifespan. Produced to the highest quality standards, our vertically stacked, in-phase dipole arrays ensure uninterrupted, reliable operation even in the harsstanding environmental conditions.

Heavy-Duty TETRA Yagi & Marine Band Antennas

Antenna Experts manufactures a comprehensive line of TETRA Marine Band Antennas and TETRA Yagi Antennas optimized for the 380-400 MHz, 410-430 MHz, 380-420 MHz, 450-470 MHz, and 806-870 MHz bands. Every TETRA antenna we produce is a marine variant, housed in extremely rigid, RF-transparent fiberglass or ABS radomes. To ensure ultimate durability in saltwater environments, we utilize premium materials like Radiating Elements - High-grade Brass, Phasing Systems - Premium Copper, Support Pipe - 6063T6 ultra-corrosion-resistant architectural anodized aluminum alloy and Mounting Hardware -Type 316 marine-grade stainless steel

 Antenna Experts Premium Range of TETRA Antenna Portfolio:

• High-Gain Fiberglass Collinear Antennas (Omni-Directional): Our broadband vertical polarized collinear antennas use vertically stacked radiating elements fed in-phase to deliver true omni-directional horizontal patterns. No field tuning is required. AC6-380-430: Delivers a constant 6dBd gain over the entire 380-430 MHz band. AC12-420: Provides a smooth VSWR and constant 12dBi gain across the 410-430 MHz band. AC12-840: A rugged 800MHz model ensuring a constant 12dBi gain over the 806-870 MHz frequency band.
• Heavy-Duty Stacked Dipole Arrays (SD Series): Designed for robust TETRA network applications, our SD series features two, four, or eight center-fed dipole antennas with molded phasing harnesses. Mounted on an aluminum boom, these vertically stacked arrays maximize omnidirectional gain while minimizing interference.
• Wideband TETRA Yagi Antennas (AY Series): Ideal for Trunked Radio TETRA applications, the AY series offers wide frequency band coverage (380-430 MHz, 410-470 MHz, and 806-870 MHz). These robust antennas provide a consistently low noise floor, essential for extended lifespan and multi-carrier transmission.
• Circular Polarized Helical Antennas (AH Series): Utilizing Circular Polarization Antenna Technology, our AH series (including the AH-405) delivers superior signal penetration through obstructions. Available in both Right Hand (RHCP) and Left Hand (LHCP) configurations. Housed in a low-profile cylindrical fiberglass radome to minimize wind loading and prevent ice formation. Uses extended stubs to provide greater gain while maintaining a wider beam-width.
• Engineered for Marine and Harsh Environments: All Antenna Experts TETRA antennas are marine variants. Whether deployed on coastal towers or offshore platforms, our antennas are completely protected within high-tech radomes that are highly transparent to RF signals. Optional 7/16 DIN-Female connectors and TEFLON dielectric coaxial cables are available for high-power handling.
