The Altronic 6405 is a compact forced-air cooled RF dummy load designed for continuous-duty operation in 50 ohm transmission systems. It provides a stable, non-radiating termination for transmitter testing, proofing and maintenance, allowing engineers to run transmitters at power without feeding the antenna system. Its combination of 5 kW rating, low VSWR and practical form factor makes it well suited to broadcast and communications sites.
The Altronic 6405 is supplied as a single high-power RF termination with a 50 ohm coaxial input connector, specified to match common transmitter output line standards such as N-type or EIA flanges depending on the chosen version. The load is intended to be connected directly to the transmitter output or to a suitable point in the RF line, providing a convenient non-radiating termination for power tests and measurements. Its forced-air cooling assembly and compact footprint make it straightforward to position within transmitter rooms where space and airflow paths must be carefully managed.
In daily use the Altronic 6405 gives engineers a dependable way to run transmitters at or near full power while keeping RF energy confined to the load. This simplifies fault-finding, alignment and proof-of-performance work without disturbing the antenna system or risking unintended radiation. The forced-air cooled design supports continuous-duty operation when required, and the oil-free construction reduces maintenance tasks associated with liquid-filled loads. For broadcast and communications facilities needing a practical, standalone high-power RF termination, the 6405 provides a robust long-term solution.
