Product overview
The HGLRC 5.8G Hammer Dual Antenna is an RF antenna accessory for airborne transmission links. Its architecture combines a dual-antenna design with dual-channel transmission, with a stated 30% coverage improvement over single-antenna systems. RF field superposition provides omnidirectional coverage intended to maintain connectivity as flight attitude changes. The design also combines low VSWR with OFDM technology to improve radiation efficiency and extend transmission range, while precision impedance matching and batch consistency testing support consistent high-frequency output.
Physical integration centers on an SMA male connector with an inner pin and RG141 cable. Total length is 170mm (±5mm), and weight is 13.8g (±0.5g). SMA LHCP and SMA RHCP configurations are listed, while the detailed polarization specification is RHCP. The specified frequency range is 5.35GHz–6GHz; gain, VSWR and radiation efficiency have frequency-specific values, including a maximum VSWR quoted at 5300MHz. The supplied package contains one HGLRC 5.8G Hammer Dual Antenna, making this an antenna component for integration.
