The Drake MN-77 manages rf radiation in the areas of impedance match to the antenna, rf power measurement, VSWR measurement, reduction of harmonic radiation, and antenna selection. |
 | 160 thru 10 Meters Frequency Coverage Without of band coverage for MARS, future band expansions and other applications. |
| Antenna Choice Matches antennas fed with coax, balanced line, or random wire. (For balanced line use optional Drake B-1000 Balun, which mounts on rear panel of MN-7.) |
| Antenna By-pass Switching unique design allows unit to be switch by-passed regardless of which antenna is in use, whether coax or wire type. No need to manually disconnect feed lines. Switch also selects various antennas. |
| Extra Harmonic Reduction to help fight TVI. Drake Matching Networks employ special "pi-network" low-pass filter type circuitry for maximum harmonic rejection. This feature alone makes the MN-7 a worthwhile investment; it is a Drake exclusive. |
| Built-in Metering-Accurate rf wattmeter/VSWR bridge is pushbutton controlled from front panel. Meter reads 0-300 watts forward power or VSWR. |
| Power Capability: 250 watts continuous. |
