At 1/4 the size and weight, the RF-1 isįar more usable that the MFJ units in outdoor or tower-top Given, but is probably longer than its competitors because of its Internal frequency counter with external signals - a feature that Other hand the high end MFJ units have a jack to allow use of the The added advantage of calculating and displaying more that justįrequency, SWR and "Resis tance." Not only that, but the digitalĭisplay is much easier to read that the analog MFj meters. Its operation is similar to SWR analyzers made by MFJ, but it has Methods are described for using displayed values toĭetermine the type of reactance present and estimating the Readings are calculated as if the measured impedance were pure SWR and rf impedance areĬalculated and displayed directly. It appears that the device performs analog rf measurements, rfĭetection and conversion to digital data, then calculation andĭisplay using the microcontroll er. Instructions mention also diode detectors and an A/D converter. To use a broadband bridge-probably resistive. Operating theory is not given in the instructions, but it appears Multiple functions and give unambiguous digital readings. Use of an microcontroller chip allows the RF-1 to perform Plug and directions for use of the analyzer to measure rf Mine also included andĪccessory kit consisting of a couple of mini-gator clips a banana The display is also used to show measured Operating frequency is displayed on its multi. The hf band in several ranges and is tuned by means of coarse and Operating controls are: pushbuttons for power on/selection ofįrequency band and mode and two knobs for tuning. SO-239 coaxial connector and a ground lug for connections on oneĮnd and a LCD display on operating controls on its face. The appearance of the instrument is deceptively simple. Power: 9 volt Alkaline battery (not included) Measurements on hf amateur radio antennas: Condensed specs are:Ĭase: 4.5x2.5x1.5 inches, black ABS plastic The Analyzer is a small hand-held device intended primarily for Helped things along by attaching a copy of an ad from QST to my Present I wanted - an Autek RF-1 Antenna Analyzer. Santa Claus was very good to me this year. Review for your edification and enlightnement :-).Īutek RF-1 Antenna Analyzer Product Review The least I can do is to present a product I've inflicted several tales on the list about the AutekĪntenna analyzer.
