PURPOSE:To simply adjust the distance between a primary radiator and a primary reflector, by fitting the primary reflector to a tip of the primary radiator via an insulator. CONSTITUTION:An insulator 7 is fitted to an open tip of a primary radiator 5 having an aperture horn and a feeding waveguide closely with its external circumference 6 and a primary reflector 8 is mounted at the tip of the insulator 7 with a plurality of screws 9, 9'. A cylindrical base 7a of the insulator 7 is fitted to said external circumference 6 freely attchably and detachably with screws 10, 10'. In providing a long insertion hole to the cylindrical base 7a of the insulator 7, the insulator 7 can be adjusted for the primary radiator 5 in the lengthwise direction, allowing to simply adjust the distance between the primary radiator 5 and the primary reflector 8. |
