Portable Antenna analyser with graphical display, up to 230 MHz.

The MFJ-226 is a battery operated antenna analyser for the frequency range from 1 to 230 MHz. Thanks to it#s design as a vectorial network analyser (VNA) the MFJ-226 is capable to measure complex values and present the results graphically as a Smith chart. Possible measurements are SWR, complex impedance (resistance and signed reactance), phase angle, return loss and much more.

Another important feature of the MFJ-226 analyser is the possibility to calibrate the system. With a measurement of open, short and load (OSL) a better accuracy is achieved. Further existing cable losses and phase shifts can be eliminated from a measurement. Calibration data can be stored for later recall for four different setups.

For measurements the MFJ-226 offers 32 memories. This is very useful when doing measurements on the road, later you can transfer the measuremnt data to a computer. Measurements are done either in the "single frequency mode" on one fixed frequency, or in the "sweep frequency mode" while sweeping between two corner frequencies. This latter mode allows for the measurement and display of SWR graphs over an entire frequency band. Measurements can also be done b computer cntrol over the USB interface.

The MFJ-226 analyser offers a graphical LC display and an easy to operate keyboard, both backlit. A USB port is used to transfer measurement data to the computer as well as for firmware upgrades. Power supply is done by two AA cells. The solid case is suitable for field-use. Size of the MFJ-226 is 165 x 80 x 32mm, the weight incl. batteries is c. 300g.

The MFJ-225 has got all functions of a standard analyser plus a variety of new functions, such as built-in LC display, 2 port VNA and USB port. The MFJ-225 does not require calibration (self-calibrating)! Very easy to use. All functions are described in the included English manual.

Two antenna analysers in one!
The MFJ-225 is a complete, self-contained analyser that is battery-powered and thus can be installed directly at the antenna. Connect the device to a PC and use the IG-mini VNA freeware to create a fully-fledged 2-channel VNA and do extensive data analysis. You can also print graphical curves in addition to your numerical results.

What is the MFJ-225 able to measure?

• SWR (1:1 to 9.9:1)
• Complex impedance (R + jX)
• Return loss (RL, 0 - 30dB)
• Phase (0 - 180°)
• Capacity (0 - 9999pF)
• Inductance (0.1 - 80µH)
• Cable length (0.5 - 45m)
• Cable loss (0 - 30dB)

Con l'MFJ-259C le tue antenne sarranno perfettamente accordate per la massima efficienza . Connettilo alla linea di alimentazione RF , setta la banda e sintonizza con la manopola - proprio come un transceiver. Leggi l'SWR e l'impedenza complessa. Sintonizzando troverai subito la frequenza di risonanza .Range di frequenza: MFJ-259C: 1.8 - 170 MHz

1.8 - 170 MHz, MFJ-269C: anche i 415-470 MHz

Misuratore di antenna compatto dalle HF fino ai 70 cm dell' UHF.

L'analizzatore di ROS MFJ-266C copre le bande che vanno dalle HF, alla banda FM, fino ai 2 metri e ai 70 cm dell' UHF. Il display LCD retroilluminato mostra simultaneamente la frequenza, il ROS e l'impedenza (parte reale e immaginaria, magnitudine assoluta). Inoltre, questo strumento può misurare capacità, induttanze, intensità di campo e frequenza e agire persino come generatore di segnali. Vi permette di effettuare facilmente tutte le misure di antenna così come le usuali misure in HF di cavi, stub, filtri e balun. Oltretutto l' MFJ-266C è facile da utilizzare.

L' MFJ-207 10-160 Meter Antenna SWR Analyzer ti da' una lettura diretta dell'SWR senza necessita' di formule o letture indirette. L' MFJ-207 puo' anche essere usato per regolare un tuner per accoppiare la tua antenna senza necessita di dover trasmettere.Il range di frequenza coperto per l'MFJ-207 e' circa da 1.75 MHz a 30 MHz in cinque bande.Cio' permette una lettura molto soft dell'SWR anche alle alte frequenze .La copertura di ciascuna banda puo' leggermente variare rispetto ai dati di targa scritti.Le bande coperte sono:
