Long -Wire Antenna Adapter Option The WiNRADiO LWA-0130 Long Wire Adapter employs a dual transformer design, making it more efficient than most conventional "longwire baluns". It is especially suitable for the AX -05E Antenna and the G303i receiver, but can be used with any third party HF radio to improve performance. A typical signal improvement using WiNRADiO Long Wire Adapter is 5dB, and in some cases up to 17dB. Advanced Digital Suite Option The WiNRADiO Advanced Digital Suite expands the power of the WiNRADiO G303i receiver with HF fax and NAVTEX decoders, a signal conditioner with numerous user -defined filters, audio spectrum analyzer and oscilloscope, audio recorder with pitch shift, and numerous others digital processing facilities. The G303i PCI-card receiver is designed with maximum reliability and I performance in mind. Not a single tunable part has been used in its design.
