The ES-820 is an inline GPS amplifier which allows extension of the GPS antenna cable. Depending upon the type of cable, 100 to 400 feet of additional cable may be added per amplifier. When using more than one amplifier, we recommend the use of the ES-AB1A GPS Amplifier Power Supply between the Master Clock and the amplifier chain. The standard ES-820 is fitted with TNC connectors suitable for direct use with RG-58 type cables. Optional adapters are available for connection to lower loss RG-8/RG213/Belden 9913 type cables using "N" connectors (order ES-820N). Typical cable extension lengths are:

RG-58: 100'
RG-8/RG-213: 200'
Belden 9913: 400'
