Abstract

The antenna is constructed as a half-wave folded-top dipole which can be pulled out of the transceiver and which consists of a lambda /4-long top part, a lambda /4 folded top following the latter and a feedline connected thereto. In the retracted state, the antenna operates as quarter-wave radiator in that the earth connection of the feeding coaxial cable is connected to transceiver earth. <IMAGE>
