Building the VK5JST Antenna Analyser

I have long needed a good antenna analyser so that I can tune my existing antennas and build better new ones. Trouble is, they can be very expensive.
All that has changed, now that there is a new kit on the market.
The new analyser covers the HF bands as well as 6m – perfect for my SOTA and WWFF needs.
I ordered mine from their website, http://www.vk5jst.com, and it arrived well packed.

The quality of kit is excellent and came well packaged.

The instructions call for the mechanical build to be tackled first; attending to the enclosure by drilling all the necessary holes and cutting out the hole for the LCD. Suggestions are provided, which I found very useful.

The main PCB is used as a template for positioning and drilling the mounting holes into the lid of the enclosure.

Cutting out the hole for the LCD screen is probably the most tricky part; I used a coping saw and although it took time, I was able to achieve a very satisfying result.

Getting the measurements right was important.

Once I had finished with the drilling and sawing, I cleaned up the mess and took a rest. The result was more than acceptable, I think.

The completed front panel.

The final job to be tackled was to cut the opening for the N-connector and tuning capacitor knob. The instructions suggested using the course wheel of a bench grinder. My initial feeling was that this would be rather ‘drastic’, but it turned out to be a piece of cake.

The bench grinder sliced through the plastic like a knife through butter.

All that was left for me to do was to complete the job using a fine file.

  1. Thanks Grant

    Just getting back into radio after a few years of quiet.

    I’ve invested in an FT-450D rather than get my current rigs repaired. Sadly, both died at around the same time so I’ve had no on-air capacity for a while

    Looking forward to hitting the airwaves again
