Re: Terry's New Plane Wave Antenna

Hi,

The files you mention are up to date. The antenna will work with any scope. The antenna's ground plane is grounded through the cable to the scope chassis.

Cheers,

Hello Terry,

I got interested in your "Large Wide-Bandwidth Plane-Wave Antenna", described here:

http://hot-streamer.com/temp/PlaneWave.pdf

and here:

http://hot-streamer.com/TeslaCoils/MyPapers/planant/waveant3.html

I`m going to take some measurements of my VTTC with this unit (I haven`t build it yet). Everything seems to be in order, but - you use Tektronix TDS210, as i see from the photos this o-scope is very small (battery-powered perhaps?) Mine o-scope was made in USSR, it has a massive _metall_ chassis (signal ground - one signal wire is tied to the chassis),
and it`s energised by the mains.

So, does all your system has the "floating" potential, or it`s connected to the ground anywhere? See - the whole capacitance of my scope chassis is not very small - can it influence the measurements anyway? And, maybe there`re some new revisions of this
antenna after this one:

"The new one is larger, quieter, better bandwidth, tougher, easier to make..."
