FoxDelta – USB Antenna Analyzer review

With antenna analyzer prices approaching the cost of a used HF rig I was on the lookout for a good balance of cost and value. I initially looked at commercially available USB analyzer, but these too had a poor cost to value ratio.

Ran across an article in a past CQ issue, reviewing a FoxDelta antenna analyser kit which on the surface looked great. The reviews were good and at $54 shipped not a lot of risk if it went wrong.

BNC connector and a LED are on the other end.

The SMD are either pre-installed, or matted to a socket which makes this a simple through hole construction project. The parts are provided in labeled little plastic bags which aligns with names on the parts list. The list in turn lists the locations for that part type.

Simple process of opening a bag and with the parts list as a guide, insert that part in each location identified. I spent a total of 5 hours over two evenings populating the board.

The operations manual has full details of the PC software and use of the Analyser. I have been having a problem with a multiband vertical having a high SWR on 10m. Something that the analyser was quickly able to confirm.

The PC interface is easy to setup and simple to use. The screen capture below is a scan of 20m.

In conclusion, fun to build, easy to use and a great value. Highly recommended.

Until next time, 73’s
