When a new ham eventually wants to get on HF, the antenna is usually the biggest source of difficulty. For a lot of people, it is often not practical to make and use an HF antenna that is self resonant due to the large size. For example, if we wanted to make a half-wave dipole for the 20m band, it would have to be 10m across, which is massive! So here enters electrically short transmitting antennas; antennas which are able to transmit on a given frequency while being less than 1/4 of the wavelength, albeit with some notable tradeoffs which we will see later. ...
