MFJ-266C HF/VHF/220MHZ/UHF Antenna Analyser
NO LONGER AVAILABLE.
MFJ HF/VHF/UHF Antenna Analyzer
1.5-185* MHz plus 220 and 300-490MHz
All the RF-diagnostic functions you need with easy-to-use MFJ-266C digital analyzer!
The MFJ-266C covers HF, VHF, plus UHFamateur and commercial frequencies with digital precision.
It also displays SWR, Complex Impedance, and Impedance magnitude simultaneously -- all on the same
easy-to-read LCD screen. Use it to measure Capacitance, Inductance, Field Strength, Frequency, plus
generate test signals. You can also fine tune stubs, analyze coax, test baluns and RF transformers, and
perform many other important RF-related tasks around the shack or on the road!
When it comes to simplicity and convenience, MFJ-266C is a winner. Not only is it easy-to-use, but fits comfortably in one hand for on-the-fly measurements on the bench or in the field. Here`s the rundown of what this compact powerhouse can deliver:
The MFJ-266C covers all bases -- 160 through 6 Meters, the FM broadcast band, Airband, 2 Meters, 220 MHz, 70 cm, plus VHF/UHF commercial 2-way frequencies:
Band A: 1.5 to 2.7 MHz
Band B: 2.5 to 4.8 MHz
Band C: 4.6 to 9.6 MHz
Band D: 8.5 to 18.7 MHz
Band E: 17.3 to 39 MHz
Band F: 33.7 to 65 MHz (gap*)
Band V: 105 to 230 MHz 220 MHz!
Band U: 300-490 MHz
The velvet-smooth 10:1 vernier drive and solid state varicap makes fine tuning a breeze, Built-in dial lock prevents accidental detuning making measurements. Switched backlighting LCD screen is easy-to-read in any light.
SWR, Impedance Magnitude, and Complex Impedance
In SWR Mode, MFJ-266C reads SWR 1:1 to 9.9:1, Impedance Magnitude 10-500 Ohms and Complex Impedance (resistance
and reactance). Best of all, it displays all three parameters simultaneously and operating frequency with one quick glance. No other low cost handheld analyzer offers this! (Note: Z-mag and R+jX not displayed on UHF).
Capacitance and Inductance
Find values for unknown capacitance in pF or unknown inductance in uH quickly. Measurements are made at RF frequencies
rather than at the low audio frequencies used by many handheld L/C meters.
Frequency Measurement, Field Strength Readings
In Frequency-Counter Mode, MFJ-266C becomes an accurate 500-MHz counter with a choice of 1-kHz or 100-Hz resolution. The
counter mode also features a high-resolution digital field-strength meter for measuring the relative intensity of incoming signals. Together, these functions are extremely useful for checking the operation of oscillators,
transmitters, as well as assessing the strength of radiated signals from antenna arrays.
Built-in Interference Detection
In Frequency-Counter Mode, MFJ tracks down powerful local signals that disrupt accurate SWR measurements. When picked
up by an antenna under test, these signals compete with MFJ-266C`s internally generated test signal to make SWR readings appear artificially high. Handheld antenna bridges are subject to additive interference, but only MFJ detects the offending signal, displays severity, and identifies frequency!
Powerful Signal Source
MFJ-266C also functions as a tunable signal source, supplying about 2 Volts peak-to-peak across the entire tuning range. You can use this signal to drive mixers, low-power amplifier stages, or filters, and use it as a source for checking antenna patterns on a range. Add a step attenuator, (MFJ-762) and it becomes a low-level signal source for testing receivers and pre-amps.
Take it With You!
You`ll love the compact size and bantam weight of MFJ-266C when perched on a tower. Also, push-button band switching lets you toggle across the spectrum with ease when tucked into cramped spaces.
MFJ-266C is ergonomic, antenna N-connector positioned on top of the case and everything else arranged and clearly marked on front panel -- right in front of your eyes.
MFJ-266C’s operating manual was professionally written and illustrated to help you understand and master every function quickly. It also includes a guide for ensuring accurate results and getting the most from the unit`s advanced features. In the back, you`ll find a one-page "Quick Guide" that reviews all controls and functions.
Many Instruments in One
Having MFJ-266C is like owning several pieces of test equipment. You get a powerful wide-range signal source, Inductance/Capacitance meter, network analyzer, RF field-strength meter and a 500-MHz frequency counter all-in-one small package.
