The new eBox Ethernet Remote Control Device for ACOM power amplifiers .

Frequency coverage: 1.8 to 30MHz and 50 to 54MHz, continuously (30 to 50MHz on request).
Antenna impedance matching capability: all impedances with 50 Ohm-SWR between 1:1 and 3:1; (for some higher-SWR impedances matching is also possible see power limitations below).
Maximum RF Input power admissible, average or continuous (no mode limitations; in brackets – PEP):

* (when tuning is possible for SWR above 3:1)

Rem: Operation at SWR above 10:1 is not permitted even though matching could be possible in some cases.
RF Input characteristics:
-Nominal impedance: 50-Ohm unbalanced;

-Connector type: UHF/PTFE (S0239A);

-Input SWR during full tuning (basic matching cycle): below 2:1

-Input SWR soon after full tuning: less than 1.5:1 (below 1.3:1 typ.).

Antenna output characteristics:
-Nominal impedance: 50-Ohm unbalanced;

-Connector type: UHF/PTFE (S0239A);

-Number of outputs – 4;

-Antenna SWR: between 1:1 and 3:1 for 100% matching, full power; for higher-SWR impedances (provided matching is possible) see power limitations above).

Full tuning duration (basic matching cycle):
-Below 10MHz: less than 5s (2-3s typ.)

-Above 10MHz: less than 3s (1-2s typ.).

RF Input power required during full tuning: 25W +3/-3 dB (12.5 to 50 W), non-modulated.
Power supply and control: available from the ACOM solid state HF+6m amplifiers through RF-output coaxial cable; +26VDC, up to 25 W consumption; control data using a FSK modem at 60 kHz.
Coaxial cable maximum length (same for RF power, DC power supply, and control):
-100 m (330 feet) for cable type RG-213.
