[TowerTalk] Coiled Antenna's

[Chris I Townsend <chris@cbnr.net>]

Hi,

I would be very grateful if someone could point me in the right 
direction to locate some relevant antenna theory.

I have come across the idea of using a 'slinky' as an antenna.  I am 
looking for some formula to calculate the effect of coiling a HF antenna 
where the coil diameter is a tiny fraction of the wavelength.

I've come across several sites that suggest lengths etc. that will work, 
but I'm interested in the theory.

Please reply to chris@cbnr.net.
