HELICAL 1.2G 11dBi 7-Turn SMA Antenna by SkyReach

The HELICAL 1.2G antenna is a high-performance circular antenna manufactured by SkyReach, designed for operation in the 740-1440 MHz range. It is a reliable solution for receiving and transmitting RHCP circularly polarized signals, combining high gain and a narrow beamwidth for precise energy direction, making it ideal for applications in unmanned systems, medium-range radio communications, telemetry, and video transmission systems.

Description and Advantages

The antenna features 11 dBi gain and a 39-degree beamwidth, providing a concentrated beam pattern with excellent penetration capability in the specified frequency range. The 7-turn design ensures stable RHCP circular polarization and an improved standing wave ratio (VSWR: 1.3), which reduces losses in antenna-transmitter/receiver matching.

Technical Specifications

• Bandwidth: 740-1440 MHz
• Beamwidth: 39 degrees
• Gain: 11 dBi
• Turns: 7
• Polarization: RHCP
• VSWR: 1.3
• Connector: SMA
• Antenna Weight: ~750g
• Quantity in Set: 1 piece

The antenna is made of materials that ensure durability and resistance to external operating conditions, while its weight of approximately 750g makes it convenient for mounting on platforms with limited payload capacity. The SMA connector allows easy connection of the antenna to most transmitters and receivers without complex adapters.

This model belongs to the category: Antennas > Circular Antennas > Helical Antenna and is suitable for use in systems where beam directionality and stable circular polarization are important. It is recommended for FPV systems, medium-range radio links, and applications requiring high signal quality and minimal matching losses.

The model is supplied by the manufacturer SkyReach and offers an optimal balance of size, weight, and performance. Thanks to its wide frequency range of 740-1440 MHz, one antenna can cover several adjacent bands without the need for replacement or modification. Pay attention to RHCP polarization when matching with other systems to ensure maximum reception/transmission efficiency.
