  • Radio system attenuator for an antenna
    Patent number: 6816739
    Abstract: A radio system having a hub transceiver and a plurality of customer premise transceivers at different distances from the hub transceiver. Each of the customer premise transceivers includes an antenna for transmitting an upstream radio signal to the hub transceiver and receiving a downstream radio signal from the hub transceiver. A selected exchangeable attenuator pad is mounted on the customer premise antenna in the path of the radiated signals for attenuating the upstream and downstream radio signals. The attenuator pad is selected in order to compensate for the different transmission path losses in order to provide a fixed predetermined signal strength in the downstream radio signals to each of the customer premise transceivers and a fixed predetermined signal strength to the hub transceiver from each of the customer premise transceivers.
