6-2. Functionsa) Antenna Impedance Matching Process: aided by a plate-load True Resistance Indicator (TRI).b) Two antenna outputs selectable by a button on the front panel.c) Protections:- Cover interlock for operator’s safety;- Inrush power-on current limited to the nominal consumption;- Control grid, screen grid, and plate currents;- T/R sequencing;- Antenna relay contacts, including RF power induced in antenna from another nearby transmitter;- Antenna matching quality;- Reflected power.d) LED bar-graphs for forward peak power and reflected power.e) Service visualization of grid 1 DC current, grid 2 DC voltage, and plate DC current.f) Tube: a single Svetlana 4CX800A (GU74B) high-performance ceramic-metal tetrode with platedissipation of 800 W, grid driven, forced air-cooling.6-3. Storage and ShipmentCAUTIONShould it be necessary to ship the amplifier, use the original packing as describedbelow.Switch off the amplifier, pull the line (mains) plug out of the outlet, disconnect all cables from the rearpanel of the amplifier (remove the ground connection the last), and then pack the amplifier in its originalcarton.a) Acceptable storage environment: The amplifier may be kept packed in a dry, ventilated and unheatedlocation (with no chemically active substances such as acids or alkalis) within the following environmentranges:- Temperature range: -40 to +70 degrees Celsius- Humidity: up to 75% @ +35 degrees Celsius.b) Shipping Size and Weight: WxDxH: 530x470x280mm, 18kg (21x18.5x11 inches, 39.6Lbs).c) All types of transportation may be used, including storage in an aircraft baggage compartment at upto 12000 meters above sea level.
