The 6dBi Optimised Helium Antenna offers +7% forward Power Transmission compared to alternative non optimised VSWR Antenna designs. 

It is a solid solution that provides extra power and coverage for Helium outdoor base stations. The antenna has an average gain of 6dBi, length 54cm, frequency range 868-880MHz and comes complete with hardware for pole and wall mounting. 

Antenna has a built-in bandpass filter that works without attenuation in the working band of the antenna and is characterized by attenuation for other frequencies. The filter, located in the antenna radiator, is a 1/4 wavelength segment shorted to the ground at 868 MHz, and a resonant slit in the socket module. Frequencies different from the antenna operating frequency are discharged to the ground. The filter attenuates unwanted signals by a few dB. It is a specialized narrowband antenna operating in a dedicated band (EU868), which allows to obtain a high signal-to-noise ratio (SNR) and maintain high sensitivity of the receiver in the device. In the construction of the heat sink, we do not use LC matching circuits (capacitance-inductance correlation) that allow for "artificial" antenna impedance adjustment and lowering the VSWR coefficient. This causes an increase in induction or capacitance, which results in "blurring" of digital signals and has a negative effect on the bit / Hz encoding and the error rate (BER). Our antenna works "clean, resistive" and has a very low self-noise figure and an excellent bit / Hz encoding ratio. The antenna housing is grounded, which protects it against electrostatic discharge(electric charges appearing on the antenna are discharged to ground). For proper operation, the mast and antenna must be grounded to the existing lightning protection system.
