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 

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.


It can be deducted if not wanted. ($25.00 credit)

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)
