RF question

Hi all,

Slightly off topic this one but I hope it will pass..
In some very simple experimentation I did some time ago I tried to light a 
simple LED from the RF field from the secondary. I did manage this with a 
lot of messing about, though my question relates to plasma globes, in that 
they also give a RF field and can light a LED just by holding it near the 
globe. Now I have measured the frequency and that was about 40khz on the 
globe, tesla secondary around 200khz or there abouts. The odd thing is 
about the plasma globe is just about anything you put near it will charge 
up, unlike the tesla secondary which needs to be in some form of tuning. 
Does anyone have any ideas why the plasma globe is "care free" of tuning ?

Also is there anyway to increase the RF power off a Tesla coil ? I know 
most want to reduce it due to loss though I find high power RF can do a lot 
of cool things and I would like to concentrate on bossting the RF power and 
not to long arcs. Can anyone point me in the right direction to do this ?

Thanks all,
Chris
