A 60MHz band four-element sleeve-type antenna equipped with a reflector and waveguide, featuring high gain and directivity.
The 4SL-060 (4SL060) is a 60MHz band 4-element sleeve antenna manufactured by Nippon Antenna. * A sleeve antenna is a broadband 1/4 wavelength linear antenna that is used in an upright position. * It is an antenna for fixed station radios. * It is a unidirectional antenna that transmits and receives radio waves from one direction. * It operates at a specified frequency within the 54–75MHz range. Please specify the center frequency (fo/MHz) when placing your order. * To enhance the gain and directivity of the sleeve antenna, it is equipped with a reflector and a waveguide, making it a vertically polarized directional antenna used for fixed stations. * The sleeve completely prevents radio wave leakage to masts and other structures, ensuring stable characteristics. * A waterproof sleeve is included, providing complete waterproofing for the feeding part (connector part). * The connector is NJ. * The compatible antenna mounting bracket is B-8-1(B), and for a mounting diameter of 48.6φ, it is B-8-1(A). * For more details, please feel free to contact us.
