Why is my calculation for added length of coax for a double cross antenna different to everyone else's?
Ham operators often tell me that comparing gain to an isotropic radiator isn't much use because it's only a theoretical antenna, is this true?
Will electrically joined dipoles of different lengths, at right angles, behave as a multiband antenna?
Exactly why do some SWR meters give a changing reading depending on the length of coax used to connect to an antenna?
What kind of loop antenna is this, and what is the relationship between its diameter and wavelength?
