摘要: A dual function antenna system and method. is provided for using a single both the reception of low frequency navigational signals, such as LORAN-C, high communications signals in VHF region. The at remote location from receiver transceiver. Both are coupled to transceiver, respectively, over same transmission line one end thereof. preamplifier increase strength signal applied line. pass filter couple prevent feedback output reaching its input. other transceiver by filter, filter. supplied with DC power line, includes current regulator so that may be used wide range supply voltages.
