HGLRC Hammer Mini 5.8GHz LHCP Antenna

Buy the HGLRC Hammer Mini 5.8GHz LHCP Compact Omnidirectional FPV Antenna for Stable Video Transmission and Lightweight Builds

The HGLRC Hammer Mini is a subminiature 5.8 GHz left-handed circular polarization (LHCP) antenna. It is designed specifically for FPV drones. Ideal for digital video systems such as DJI and Walksnail that use LHCP. The 2.5 dBi gain provides an excellent balance between range and directionality. Minimal weight and compact dimensions make it an excellent choice for lightweight racing and freestyle drones.

• Compact size and light weight. The antenna weighs only 1.5 grams, making it ideal for ultra-light racing drones where every gram counts. Total antenna length - 130 mm.
• Circular polarization LHCP. Left circular polarization effectively suppresses reflected signals and interference, providing clear and stable video images, especially in densely built environments or when flying long distances.
• Wide frequency range. The antenna operates in the 5500–6000 MHz range, which covers all popular 5.8 GHz FPV channels and ensures compatibility with most video transmitters.
• High build quality. The antenna is housed in a durable black radome made of ABS plastic. Its rigid tube design ensures a secure fit on the drone..
• Connection options. Various connector types available (SMA, MMCX, u.FL), which allows you to select an antenna for any video transmitter.

How the HGLRC Hammer Mini antenna works

The antenna converts the electrical signal from the video transmitter into circularly polarized radio waves (in this case LHCP). Circular polarization effectively suppresses reflected signals from the ground and obstacles. They are the main cause of interference in FPV systems. Thanks to the 2.5 dBi gain, the antenna concentrates energy in the desired direction, increasing the range of reliable reception. You get a stable video image with minimal interference even in difficult flight conditions.

About the manufacturer HGLRC

HGLRC is a famous Chinese brand founded in 2016. He specializes in the development of high-performance FPV components: drones, flight controllers, ESCs and video transmitters. The company actively cooperates with professional pilots, which allows it to create products that precisely meet the needs of the market. The Hammer Mini series antennas are the result of this approach, offering pilots a reliable and efficient video transmission solution.

Features of the Hammer Mini range

The Hammer Mini line is represented by antennas with both right-handed (RHCP) and left-handed (LHCP) circular polarization. LHCP model is ideal for use with DJI and Walksnail digital video systems, as well as analog systems where left-handed polarization is required.

The antenna is available in several modifications, differing in connector type: SMA (for connection to glasses or external modules), MMCX (for compact VTX) and u.FL (for direct soldering to the board). Version V2 received a slightly modified design and improved characteristics, including an expanded frequency range of 5000–6000 MHz.
