It's likely unsafe. 

likely? how is this? do you have any measured data to back this up? how did you come to this conclusion?

Thanks to all

i will try the pancake coil and read the Dr Stiffler doc

I have to go away for some days    i will resume the experiments next week

lot of fun to all

i beleave them to be dangrous .. !

it all depends upon there freq of operation ...

if your antena was tuned to your brainwaves ...  perhaps there risks..  nevermind all the weird crap that can happen from playing air core

but agin all has its place ...

i still perfer a self running thing that you just bring with ya...

and contained in a core ..

i have done things with air core coils i did not like .. and we wont go to details .. 

yes they can cause odd effects ...

and if there children in the house ...

IT IS BEST NOT TO PLAY THAT CARD ..

here is a simple event that may happen ..  you will hate yourself for life ...  so be wize ..

say i was playing with a high power air coil .. just playing round with a coil un aware of the effects of such a thing .. and my kids come into the room  and say daddy lets play they grab the door handel you are in the middle of an expairment ... you had no idea the door knob had 50 000 volts sitting on the surface .. your child  just found out ... THE WRONG WAY ...

NOW HOW DO YOU FEEL ?

Spot on IST,

All these experiments using open ended antenna's can not only be a possible or probable health hazard at close proximity but as IST mentioned the build up of potential static charges within the  vicinity could be fatal!!! One other point worth mentioning here to be critically aware of! These are RF transmission devices in various forms which have the capability of distant radio signal transmission across the radio frequency networks!! Operating such devices can create untold havoc with sensitive equipment over a considerable distance.

I whole heatedly agree with ist in experimenting with closed loop inductive type systems. Not for me to discourage experiments... only to re iterate this GOOD ADVICE
