MFJ-209 SWR Analyzers are easy-to-operate, versatile test instruments for analyzing nearly any 50 ohm RF system. They operate on frequencies between 1.8 and 170 MHz and may be used as a low-level signal source. MFJ-209 analyzers combine three basic circuits: a wide range oscillator, a 50 ohm RF bridge, and a calibrated bridge unbalance ...

MFJ-209 SWR Analyzer Instruction Manual The MFJ-209 measures actual SWR. The load must be 50 ohms of pure resistance for a meter reading of 1:1 . The common misconception that 25 ohms of reactance and 25 ohms of resistance in a load will give a 1:1 SWR is absolutely untrue. The actual SWR in this condition will be measured as 2.6:1 .

The MFJ-209 SWR Analyzer is an easy to operate, versatile test instrument for analyzing nearly any 50 ohm RF system on frequencies 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.

The MFJ-209 is a pretty good product when it comes to analyzing. I honestly feel the comments said on this page are a little harsh in nature. The 209 is designed to be a, "poos mans" analyzer. The unit is pretty simple and can be mastered in a few minutes. Although the unit lacks some of the bells a whistles found the the 259, it seems to get ...

The MFJ-209 may be used to adjust or measure the following: Antennas: SWR, resonant frequency, bandwidth, efficiency Antenna tuners: SWR, frequency Amplifiers: Input and output networks ... MFJ-209C SWR Analyzer Instruction Manual 6 SWR and the MFJ-209C Some understanding of transmission line and antenna behavior will be necessary to use the ...

The MFJ-209 Antenna Analyser is an easy to operate, versatile test instrument for analysing nearly any 50 ohm RF system. Covers all Amateur bands between 160m to 2m. For precise frequency measurement the station transceiver or small portable receiver may be used as a monitor. Key Features/Specifications: Frequency Coverage 533kHz-230MHz

2025年1月26日 · The MFJ-209 SWR analyzer provides continuous coverage from 1.8 to 170 MHz with smooth vernier tuning. Same as the MFJ-249, but without the LCD frequency counter. 4 x 2.5 x 6.75 inches. Requires 8 AA cells (not supplied) or optional MFJ-1312D. More Radio Amateur MFJ Meters MFJ-201 (MFJ 201 ...

The MFJ-209 combines three basic circuits: a wide range oscillator, a 50 Ω RF bridge and a calibrated bridge unbalance indicator. This combination of circuits allows measurement of the SWR (referenced to 50 Ω) of any load connected to the ANTENNA connector. The FREQUENCY switch selects the following frequency ranges:

The MFJ-209C is a compact and versatile SWR (Standing Wave Ratio) analyzer designed for amateur radio enthusiasts and professionals. It provides precise analysis of RF systems across a wide frequency range, covering all amateur bands from 160 meters to 2 meters (533 kHz to 230 MHz). The device operates without an LCD display, instead relying on ...

MFJ-209C SWR Analyzers are easy to operate, versatile test instruments for analyzing nearly any 50 ohm RF system. They operate on frequencies between 0.530 and 230 MHz and may be used as a low level signal source. MFJ-209C analyzers combine three basic circuits; a wide range oscillator, a 50 ohm RF bridge, and a calibrated bridge unbalance ...
