ES-1A

Radio / Antenna Selector

Switch between 2 radios and 2 antennas

This product allow radio operators to switch between multiple radios and antennas. Typically they are used with a power linear amplifier. The amplifier input can be switched between 2  radios / transceivers / exciters. The amplifier output can be switched to one of 2 antennas. The device can be used without an amplifier, when the input is simply bypassed to the output.

WHAT'S IN THE BOX 



    • Use this device to easily switch the amplifier input between two radios.
    • 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.

Two versions are available: ES-1A (2000 W), ES-1ASP (5000 W).

They have identical marking and specifications except for output power capability, see detailed specifications.

Remote Head (Optional):  $25.00 

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.

Unused input: grounded
Output power: 2000 W continuous, 3000 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 150 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)
