Great suggestion from W5UN! I just did this to my VA1 and then used a soldering iron to smooth any sharp projections above the case. BTW, I omitted one other feature I like about the VA1. You can cha

I wish the review had tested the "antenna" analyzers on *antennas*, not laboratory loads. All of these meters are seriously degraded by nearby broadcast stations. My MFJ-259 is useless at my QTH. The

Gents: I do the same thing (passive plug in power socket) on my '259. I also suggest you tether the plug to the case with a nylon thread, etc. so you don't lose it when up the tower! 73 de Gene Smar

One of the nifty features of the Autek VA1 is the F-1/4 mode. Use this mode to set the autek to calculate the factors at the other end of the feedline. Adjust the frequency to the 1/4wL of the line c

Hi all, Regarding the thread about antenna analyzers, I came across a "miniVNA" which is manufactured and for sale in Europe at a reasonable price. The advantage of this unit is that it is a two port

I have found that antenna analyzers can get screwed up on long antennas if there are nearby transmitters; AM stations or any other transmitter that can swamp out the input to the analyzer. I live 1/

I can vouch for the AA-55 Zoom, although it is not without flaws. I live 5.9 miles from a 50KW BC station on 1550 kHz.  On my 160-meter inverted-L they are 70 dB over S9 on a calibrated K3, that's 70

At this location, the VNWA is a bit squirly near the BC band but with a single L/C notch added at the device input (within the cal plane), it works fine. The AA-55 Zoom I have is immune and is the my

I can now verify that the FA-VA5 does just fine on my 160 meter inverted-L. As an aside, we've had some rain here in Tucson lately and I've observed a decrease in the feedpoint Z of about 5 ohm due t
