The antenna features a narrow beamwidth and high front-to-back ratio to minimize interference and enhance signal clarity
designed to allow CDQ style whips to be laid down when not in use
making it easy to upgrade existing installations without the need for extensive modifications
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
With a robust 7 dBi gain and omni-directional radiation pattern
RFI SP0000-7610-02 Attenuator, 10 dB, DC-2.5 GHz, 50W, N Male/Female marine-antennas The antenna features a narrowThe 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
