Hi John,
It looks professional! What is the maximum spark length you can achieve?
You are using a motor and a rotating contact to switch the primary to a
capacitor bank?
Would be interesting if i would do the same on my VLF kite antenna ;-)
Would give a nice broad spectrum, hi.

Hello Stefan,
You wrote:> Just like Tesla transformers are fed with a primary winding of
some turns, something between 5 and 20 probably.
Take a look on my web site for pictures of my 3 KVA Tesla coil which shows the
primary-secondary coupling:

Fine tuning is required to get the maximum streamer length and a tap move of
only a few inches can make a HUGE difference.
On my LowFER beacon I couple the final to the bottom of my loading
coil/variometer with three turns wound to sit in the
"valley" that is between the loading coil's winding of #12 THHN wire. I'm sure
it would work at higher power.
