Wanna make the thing 2 feet longer? Easy, just decrease the amount of inductance in the 'coil' by an appropriate amount (not feet/inches, but inductance). Resonance stays the same just length is changed. Any appreciable difference in radiation? Probably not, but I have no sure idea.
The difference in 'size' of the loading coil makes up for the lack of length, and visa-versa.
