Tuning To A Quarter Wave

Nice thread on how short SSB antennas operate and why. The discussion is concerning antennas that are shorter than a quarter wavelength. It’s a bit technical, but you might find it helpful if you are into SSB.
“It may seem like semantics but there are a lot of people that get confused and think that when making the system resonant with a shorter antenna that the antenna is really the same as a quarter wave length antenna when there is a loading coil. It is far from that. Its radiation resistance and its feed point resistance are both much lower.”
