This wide-band helical antenna propagates around tunnel bends in a Non-Line of Sight scenario and provides immunity to many of the signal disrupting objects such as trains and drilling machinery which appear to obscure the tunnel
and long-haul directional communication systems
The antenna features a narrow beamwidth and high front-to-back ratio to minimize interference and enhance signal clarity

RFI SP0000-7610-02 Attenuator, 10 dB, DC-2.5 GHz, 50W, N Male/Female marine-antennas This wide-band helical antenna propagatesThe RFI SP0000 7610 02 Attenuator is a high quality 50 Ohm RF Coaxial In Line Attenuator with a fixed attenuation value of 10 dB. Designed for a frequency range of DC to 2. 5 GHz and a power rating of 50W, this attenuator features N male and female connectors. It is primarily used in RF multicoupling, bench tests, and measurement applications. The full range of in line attenuators are air cooled through natural convection with conservative power to
