I have constructed a mono band 28 MHz coaxial dipole (flowerpot antenna) for the southern hemisphere summer E season.
The 2nd and 3rd days of summer have shown promising results for the next two to three months. Whilst VK doesn’t have the ham operator population density as that found in the northern hemisphere, if you are patient, pick the right time for sporadic E to form and keep a close eye on Australia’s space weather forecast, you can qualify a summit on 10m with four unique QSOs.
The SOTA activator map shows the antenna has a good omnidirectional radiation pattern working VK4, VK5, VK7 and ZL out to 2100 km. SOTA maps acknowledged.
