Radio communication device
First Claim
1. A radio communication device, comprising:
- a controller;
a transmitter coupled to said controller; and
an antenna mount having a plurality of contacts, at least one of said electrical contacts being coupled to said controller and at least one other of said electrical contacts being coupled to a reference voltage, wherein said electrical contacts provide a signal indicative of an incorrect antenna selection of an antenna mounted to said mount, and wherein upon receipt of said signal indicating incorrect antenna selection said controller disallows transmission of radio frequency signals by said transmitter.

Abstract
A radio communication device (10) has a controller (11), an antenna mount (12), a reference voltage source (13), a voltage bias supply (14), transceiver circuitry (15) and an annunciator (16). Device (10) also has an antenna (17) that is detachably mounted to antenna mount (12). The base of antenna (17) has a conductive track (19) which is selectively insulated. Uninsulated portions of conductive track (19) connects electrical contacts on antenna mount (12) such that a code signal can be provided on signal lines connecting antenna mount (12) to controller (11). The electrical contacts are distributed on a contact housing (30) of antenna mount (12). In response to the code signal, controller (11) controls annunciator (16) to provide an indication to a user of device (10) whether antenna (17) is selected appropriately or improperly connected. The code signal is provided independent of radiofrequency signals received or transmitted via transceiver circuitry (15).
