Antenna terminology: Part 15.219 LPAM "dipole"

John · 2025-01-21T01:49:08Z

I saw this from HB... 'The total length of the transmission line, antenna and ground lead (if used) shall not exceed 3 meters' This long wire is going to be considered a radiating element which creates an unbalanced dipole antenna. Emphasis added. This is obviously a topic with many facets. Concerning the use of the word "dipole" I wanted to ensure everyone knows that one of the Procaster or Rangemaster devices atop a tall post with ground wire to ground, is still a monopole (not a dipole) by definition since feeding a monopole (or dipole as well) is possible anywhere along the conductor without changing the primary definition of the antenna. Yeah it's still a longer than 9m monopole antenna, but a monopole nonetheless.

@richpowers - I'm assuming he means the US Government.

@rugster I would prefer to politely discuss than simply have the forum sysop rant about us being a pirate for bringing it up, you scallywag! There is another [cough] place that this happens.
