Easy to Operate
The TRI is a powerful tuning aid that, together with the automatically controlled input attenuator, helps the operator to quickly and precisely match the antenna impedance to the optimum tube load impedance (5-10 seconds typically). The auto-operate function (when enabled) maintains the amplifier in the OPERATE mode for you, thus avoiding unnecessary manual operations.

No Antenna Tuner Needed
No heavy outboard antenna tuners required for antenna VSWRs up to about 3:1. ACOM 2100 amplifier will enable operator to change antennas virtually instantaneously and allow the operator to use your antennas over wider frequency ranges.

User Friendly Amplifier
ACOM 2100 is the amplifier that is both user friendly and that looks after itself. ACOM 2100 is designed to safely withstand up to 400W reflected power, up to 100 milliseconds duration of drive spikes, drive RF “tails” after a PTT or KEY release, operator’s inadvertent tuning errors etc. The amplifier also will not cease to function with a “soft” AC mains and will deliver more than half power at only 85% of nominal mains voltage. It can withstand voltage drops (down to zero Volts) for up to 10 milliseconds and can tolerate 15% mains voltage spikes, which is especially important on field day, during DXpeditions, and at portable operating events where emergency power is relied upon.

OLED Comment Display
All amplifier status indications are displayed on the dot matrix, high brightness, high contrast OLED display. The upper line on the OLED display always reads pthe eak forward output power. LED indicators are provided for: OPERATE mode, attenuation-on, transmit, selected antenna output, and ON/OFF conditions.

Three Antenna Output Ports
Three antenna outputs are selectable using a push-button on the front panel.

Easy Maintenance
Data regarding amplifier internal status is stored in a nonvolatile memory for 7 of the most recent auto protection trips. This information can be forwarded to your dealer for diagnostics.

Virtually Silent QSK
The input bypassing and vacuum antenna relays are virtually silent even in the CW QSK mode thanks to specially designed mounting hardware.

Broadband Input Matching
Resulting in very good load to the transceiver over the entire spectrum 1.8-54MHz.

Single 4CX1000A Tube
Uses a ceramic and metal radial beam tetrode with plate dissipation of 1000W which is specially designed for class AB1 RF linear amplifier operation.

Tube Protection
Permanent monitoring and protection of plate and grid voltages and currents, reflected power and the exhaust air temperature.
