An amateur regulatory constraint of 1 watt eirp limit starts to bite in to the transmitter power budget for taller (more efficient) antenna systems. Bites in even more with a smaller antenna surely!
Bites in even more with a smaller antenna surely! What I meant to suggest was that a small antenna needs a great deal of applied power to achieve a radiated power of 1 watt. For most hams, it is impr
I also believe that all short verticals have the same basic radiation pattern (the upper hemishere of a doughnut, with low angle suckin if ground loss is significant). I was privileged to see Dud Ch
