31 Oct 2013 – A Video outlining operations of the MFJ antenna analyser

Unfortunately, the speaker originally scheduled  was unable to make it. As a fill in we used the evening to watch a video of the many operations that can be preformed using the popular MFJ 259B antenna analyser.  Members found that it is possible to do operations other than just check the SWR.

Using this analyser can take the guesswork out of building and adjusting matching networks and baluns. We found we could measure the distance to a short or open in faulty coax or measure the length of a roll of coax, or coax loss, velocity factor, and impedance. We found we could measure inductance and capacitance or measure the resonant frequency and approximate Q of traps, stubs, transmission lines, RF chokes, tuned circuits and baluns. A useful options told how to adjust an antenna tuner for a perfect 1:1 match without creating QRM.

 Ian, G1JCC then gave a roundup of our week-end’s activity in the CQWW SSB contest. The score looked encouraging and most members agreed they had had a very good weekend in spite of the wind and rain that resulted in some antenna damage.
