Hi Dave,

Is it ok that I send the pictures to your private e-mail adres?
Now at this time I dont have A website to put it on.
You are free to do with it what you want.

Frank
How about a picture of the ballon/corona ring -I think we all would like to see what it looks like.
Someone here can no doubt post it where we can all access it?

Hi,

Thanks Michael, Stephan, Markus and Nicolas for your report on todays test this erly morning.
This morning there was absolutely no wind and I tried my
experimental aluminum top wire under a Helium filled balloon.
The balloon was hanging during mij whole transmission on 136.3205
Khz almost straight above mij aerial mast at 45 meters high.
My telescopic mast itself is 22 meters high, the balloon is 70 CM
in diameter and lifts up 23 meters wire and a smal corona ring of
12 CM.
My reception increeses enormous with this topwire and I did not
expect that the TX works also good.
The aluminumwire is very thin en having a high resistance, and my
earth system will be too small for this large aerial system.
I was surprised that this thin wire works so well with only the
small corona ring as top capacity.
The aerial current was around 3 Ampere, and the loading coil needs
no impendance transformer to get a good SWR.
73, from experimental station PE1RRF.

Ps. I live in a very industrialised area with heavy steel constructions nearby my QTH, I think that makes the difference in aerial height bigger than normal.
