The antenna arrangement has a first antenna (12) connected to a radio telephone via an antenna line (22) for optimal link quality. There is a second antenna (14) to enable telephony with limited link quality if the first antenna fails. An electrical switch (30) is provided to switch the second antenna to the radio telephone if the first antenna fails. The first antenna is attached to the vehicle by a breakable attachment element (36), and the switch automatically connects the second antenna to the antenna line if the attachment element breaks |
