MFJ 994BRT TUNER (HF 600W INTELLITUNER)
MFJ 994BRT TUNER, HF 600W INTELLITUNER
Description
-
The MFJ-994B IntelliTuner lets you rapidly tune unbalanced, single-wire, or balanced (with external balun) antennas automatically. MFJ's exclusive Instant Recall, IntelliTune and adaptive Search algorithms give you fast automatic tuning with more than 10,000 non-volatile VirtualAntenna memories. There are four banks of memory,and each memory bank has over 2500 non-volatile memories for tuner settings. The MFJ-994B IntelliTuner includes a highly efficient switching L-network with wide matching capability, 1.8 to 30 MHz coverage, cross-needle power meters, an accessory remote control port, a radio interface port, and heavy-duty 16 amp/1000 volt relays. It is rated at 600 watts PEP SSB, 600 watts CW, and 500 watts continuous carrier modes. This makes the MFJ-994B perfect for use with modern high power output transceivers and Ameritron AL-811/ALS-600/ALS-500 amplifiers, as well as other popular HF power amplifiers limited to no more than 600 watts output power.
