The MFJ-266C covers all bases -- from 160 meters through 6 meters, the FM broadcast band, Airband, 2 meters, 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: 108 to 230 MHz
Band U: 300-490 MHz

The MFJ-266C covers HF, VHF, 220 plus UHF amateur 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! The 10:1 vernier drive and solid state varicap makes fine tuning a breeze, and a built-in diallock prevents accidental detuning while making measurements. Switched back lighting makes LCD screen easy-to-read in any light. 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).

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. 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.

The MFJ-266C even 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.

The MFJ-266C requires eight optional AA NiMH or NiCad cells, optional MFJ-18650 3.7V 3000 mAh rechargeable Li-ion battery, or may be operated from the optional MFJ-1312D power supply (see below). Compact 3 3/4W x 6 1/2H x 2 3/4D inches. Weighs 1.32 lbs. Draws 30 mA in counter mode and 140 mA in analyzer mode. Includes N-to-SO-239 adapter.
