New mfj-209 1.8 - 170 mhz swr analyser ( )
THE MFJ-209 SWR ANALYZER IS AN EASY TO OPERATE, VERSATILE TEST INSTRUMENT FOR ANALYZING NEARLY ANY 50 OHM RF SYSTEM ON FREQUENCY BETWEEN 1.8 AND 170 MHz. IN ADDITION THE MFJ-209 CAN BE USED AS SIGNAL SOURCE. THE MFJ-209 COMBINES THREE BASIC CIRCUITS: A WIDE RANGE OSCILLATOR, A 50 OHM RF BRIDGE, AND A CALIBRATED BRIDGE UNBALANCE INDICATOR. THIS COMBINATION OF CIRCUITS ALLOWS MEASUREMENT OF THE SWR (REFERENCED TO 50 OHMS) OF ANY LOAD CONNECTED TO THE ANTENNA CONNECTOR. THE MFJ-209 COVERS ALL HAM BANDS FROM 2 METERS TO 160 METERS. THE DIAL CALIBRATION IS APPROXIMTE AND FOR REFERENCE ONLY. THE ACTUAL FREQUENCY MAY VARY FROM WHAT IS MARKED ON THE FRONT PANEL. THE MFJ-209 FREQUENCY SWITCH SELECTS THE FOLLOWING FREQUENCY RANGES: 1.8 - 4 MHz..4 - 10 MHz, 10 - 26.2 MHz, 26.2 - 62.5 MHz, 62.5 - 113 MHz, 113 - 170MHz. A FREQENCY COUNTER CAN BE CONNECTED TO THE "FREQ. OUT" JACK (RCA PHONO) TO GET A MORE ACCURATE READING OF THE FREQUENCY. AS AN ALTERNATIVE TO A FREQUENCY COUNTER, YOU CAN ZERO BEAT THE OUTPUT WITH HF RECEIVER. THE MFJ-209 CAN BE USED TO ADJUST OR MEASURE THE FF: ANTENNAS: SWR, RESONANT FREQUENCY, BANDWIDTH, & EFFICIENCY... ANTENNA TUNERS: SWR , FREQUENCY...AMPLIFIERS: INPUT AND OUTPUT NETWORKS,...COAXIAL TRANSMISSION LINES: SWR, VELOCITY FACTOR, LOSSES, & RESONANCE.....BALANCED TRANSMISSION INES: IMPEDANCE, VELOCITY, & RESONANCE...MATCHING OR TUNING STUBS: SWR, RESONANT FREQUENCY, & BANDWIDTH...TRAPS: RESONANT FREQUENCY,..TUNED CIRCUITS: RESONANT FREQUENCY,...SMALL CAPACITORS: VALUE,...RF CHOKES AND INDUCTORS: SELF RESONANCE, SERIES RESONANCE, & VALVE,...TRANSMITTERS AND OSCILLATORS: FREQUENCY.
