Abstract:
1. An antenna connection detection system for confirming connections of two antennae to a radio receiver, comprising: a receiver having a first antenna connection port and a second antenna connection port; a first antenna and a second antenna; and a circuit via which the first and second antennae are in communication with the receiver, wherein the receiver supplies a first voltage signal to the first antenna connection port and detects whether a second voltage signal is present at the second antenna connection port, thereby confirming that both the first and second antennae are connected to the radio receiver, wherein the circuit comprises a low noise amplifier (LNA) module located between the first and second antennae and the receiver, and wherein the circuit further comprises a voltage regulator that provides a regulated voltage to the LNA module, the regulator being powered by the first voltage signal.
