BUSHING INSULATOR FOR CONNECTING ANTENNAS Russian patent published in 1999 - IPC

FIELD: antenna engineering for vehicles and miscellaneous moving objects. SUBSTANCE: bushing insulator has insulating link secured in metal partition and metal capacitor plates mounted on opposite edges of link and connected to respective antenna wires. Central part of link is solid insulating cylinder placed on both sides of partition with its axis perpendicular to link surface; capacitor plates are made in the form of metal shells fitted onto cylinder ends. Metal rod is arranged inside cylinder along its axis. EFFECT: reduced diameter and improved mechanical reliability of insulator; facilitated antenna tuning. 2 dwg
