what is the difference between loaded and unloaded monpole
?
:D
?
:D
A loaded monopole antenna has a coil (inductor) in it.
is the coil is used to resonate with the capacitance of the monopole at desired freq so that the ant become pure resistive?or what?

yes
how do i calculate the radiation resistance for loaded or un loaded monopole? also how do i calculate the cap?
does any one have a program to do this stuff?
also a monopole depend on the image theorm so i need a vertual ground how do i make it practically?
