Abstract

A three-band automobile antenna assembly including an antenna mast (10) made up of two slidably and coaxially connected antenna tubes (11, 12), one of which negates a reversed-phase current for the telephone, and an antenna accommodation tube (13) which houses the antenna mast (10) therein in such a manner that the antenna mast (10) is freely retracted into and withdrawn from the tube. The antenna assembly further includes a separator (81, 82) which is connected to a feeding section of the antenna accommodation tube (13) to separate three bands consisting of telephone, FM and AM waves, and a mount (14) made primarily of plastic to mount the antenna accommodation tube (13) to the vehicle body (15). The electrical length between outer conduc­ tor of the feeding cable (21) and vehicle body (15) is set to be 0 to X/2 so that the impedance of ground circuit is substantially zero.
