MFJ 266C HF/VHF/UHF Antenne Analyzer 1.5-65, 105-230 MHz plus 300-490 MHz + 220 MHz band

Met de nieuwe en eenvoudig te bedienen MFJ-266 digitale analyzer beschikt u over alle elementaire RF-diagnostische functies om metingen aan o.a. antennes te kunnen uitvoeren!

De MFJ-266C is geschikt voor metingen op HF, VHF, plus UHF amateur en commerciële frequenties met digitale precisie. Het toont de SWR en tegelijkertijd de complexe impedantie en impedantie magnitude - allemaal op het gemakkelijk af te lezen LCD-scherm. Gebruik de analyzer ook voor capaciteit-, zelfinductie-, veldsterkte en frequentiemeting, plus het genereren van een testsignaal. U kunt ook stubs fine-tunen, demping- en foutmeting bij coax, testen van baluns en RF transformatoren, en het uitvoeren van vele andere belangrijke RF-gerelateerde taken in de shack of in het veld!

Frequentie bereik

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
Band U : 300-490 MHz

The velvet-smooth 10:1 vernier drive and solid state varicap makes fine tuning a breeze, and a built-in dial lock prevents accidental detuning while making measurements. Switched backlighting makes LCD screen easy-to-read in any light.

SWR, Impedantie Magnitude en Complexe Impedantie

In de SWR Mode, meet de MFJ-266C SWR van 1:1 tot 9.9:1, Impedantie Magnitude 10-500 Ohm en complexe Impedanties (reeel en imaginair). Alle drie parameters en de werkfrequentie tegelijkertijd in één oogopslag. (Opmerking: Z-mag en R+jX worden niet getoond op UHF).

Capaciteit en Zelfinductie

Met de MFJ-266C vindt u snel de waarde van onbekende capaciteiten en zelfinducties. In tegenstelling tot de eenvoudige L/C meters waarbij deze op een LF frequentie worden bepaald, kunnen deze met de MFJ-266C op iedere ingestelde RF frequentie worden gemeten.

Frequentie- en veldterktemeting.

In Frequency-Counter Mode, MFJ-266 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, the MFJ-266 also tracks down powerful local signals that can disrupt accurate SWR measurements. When picked up by an antenna under test, these signals may compete with the analyzer's internally generated test signal to make SWR readings appear artificially high. All handheld antenna bridges are subject to additive interference, but only the MFJ-266 can detect the presence of an offending signal, display its severity, and identify the operating frequency!

Powerful Signal Source

The 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 especially appreciate the compact size and bantam weight of the MFJ-266 when up on a roof or perched on a tower. Also, push-button band switching lets you toggle across the spectrum with ease when tucked into cramped spaces.

User-Friendly Layout

MFJ-266C is ergonomic, with the antenna N-connector positioned on top of the case and everything else carefully arranged and clearly marked on the front panel -- right in front of your eyes.

The operating manual of the MFJ-266 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 the 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. The more you use it, the more uses you'll find for it!

Bullet Proof Construction

Features like the rugged aluminum case, solid-state band switching, robust internal construction, and solid-state LCD display ensure that minor bumps and drops won't faze your unit in the least. In fact, you can expect it to hold calibration and deliver reliable service for years to come.

Vital Statistics

MFJ-266C can be powered from eight internal AA alkaline batteries or from optional 12VDC/240 VAC adapter, MFJ-1312DX. With the long storage life of alkaline batteries, your analyzer will always be ready to go when you are.
