ES-1ASP, User Manual, Power cable (ES-1A shown)

  • Use this device to easily switch the amplifier input between two radios.
  • One radio can be switched between two amplifier inputs
  • Switch the amplifier output between two antennas, by front panel switches.
  • Remove the coax cable clutter
  • Use the optional Remote Control to further tidy up your cables: place the Radio / Antenna Selector behind your amplifier and use the remote control, with no need to access the Selector front panel.

ES-1ASP uses a vacuum relay for antenna switching and it can handle 5000 W output power (6000 W peak).

Remote Head (Optional):

ES-1A and ES-1ASP have toggle switches and LED indicators on the front panel.

They can be used without a remote control.

The remote head provides identical switches and indicators in a small enclosure which can be kept near the radio or amplifier, while the main unit is at the back, with all the heavy cables.

About 50% of the customers are getting the remote control together with their ES-1A / ES-1ASP.

It can be ordered at a later time, but there are additional shipping costs.
