The team today undertook the first set of tests on the elements that will form the basis of our 30m 4-square array that we are planning on taking to Tonga!
The first challenge was to build one of the elements and validate the mechanical and the electrical characteristics. We were looking for a 50 ohm match point so that it would work properly with the 4-square array and were very happy when it matched almost spot on. We have left the radiator a bit long for now as when we add the other three elements we know the impedance will change.
We also make some more progress on adapting the CrankIR to cover 160-10m on a 12m Spiderbeam pole as well. More on that experiment in the coming week!
