The main data kept in a log is typically: time when the contact was made in UTC as universal world time place (freqency) where the contact was made operation mode (the way the information was modulated to the carrier frequency) …
UHF Ring Antenna – Easy as Pie, round as PI().
A horizontally built vertically polarized antenna.. The halfwave ring antenna was first patented by J.M Boyer in 1963 in the US. Although it looks „very horizontal“ it has vertical polarization! The circumference of the radiating ring is Lambda/2 so the diameter of the ring can be calculated as Lambda/(2*PI). The ring is at …
