• 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.

Typical use: ES-1ASP Wiring

ES-1ASP Specifications

• Input power: 200 W maximum , 50 Ω load, non-switching
• Unused input: grounded
• Output power: 5000 W continuous, 6000 W peak, 50 Ω load, non-switching
• SWR: Better than 1:1.05, 1 MHz to 30 MHz, Input (Radio) and Output (Antenna)
• Power requirements: 12 Vdc, 11 to 15 V range, up to 250 mA current
• Protection: changing input or output is inhibited when transmitting – PTT is low (<1 V)
• PTT1 and PTT2 RCA sockets output a weak voltage of about +3.6 V. When pulled low, the current is <1 mA
• Provision for optional ALC connections
• Designed and manufactured in Australia

NOTE:

PTT must be connected for this protection to work

The LED’s are following the switch position even with PTT low

(only the relays are inhibited, not the LED’s)
