ES-1SP ES-1 Radio / Antenna Selectors

• 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-1 (2000 W), ES-1SP (5000 W).
They have identical specifications except for output power capability, see detailed specifications.

Specifications

• Input power: 200 W maximum , 50 Ω load, non-switching
• Output power ES-1: 2000 W continuous, 3000 W peak, 50 Ω load, non-switching
• Output power ES-1SP: 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 supply: 12 Vdc, 11 to 15 V range, up to 150 mA current (250 mA for ES-1SP).
• 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
• ES-1 can be converted to ES-1SP

Notes

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)
