[TCML] Where to mount the HV Transformer? Under the coil or otherwise?

[Jeremy Scott <supertux1@xxxxxxxxx>]

One of the decisions I'm about to make for my new coil is where to put the HV transformer in relation to the other components. I've seen two designs:

1) HV transformer under the coil.

The HV transformer is under the coil. Long, heavy gauge 120V wire, short section of high voltage wires from the HV terminals to the tank. 

2) HV transformer not under the coil.

The HV transformer is on a pad or enclosure that is located closer to the control panel. Shorter section heavy gauge 120V wire, longer section of high voltage wire. 

I was considering doing option 2 because it uses fewer feet of the thick 120V power cable ($) and allows more space under the coil for the RSG and caps. What sort of cable do you use for the HV secondary, considering that it will most likely be very long and lay on the ground? (Perhaps in a long length of PVC pipe.)

I read somewhere that two lengths of plain TV or network coax cable works, where the center conductor carries the high voltage and the braid is connected to the RF ground at the coil. Does this work, and if so, at what power levels?
