Cart for coil

Quoting Ed Sonderman:

Generally speaking, as long as you are off of the floor by the
same height as the secondary is long, you are avoiding most of
the inductive effects of the ground. This rule pretty much covers
medium powered 1/4 wave coils. On lowered powered coils the field
flux is weaker and these coils may be placed closer to the ground
without problems. You just want to be sure that the field flux
does not couple into the concrete, earth, etc..

I sure did!

You will know your neighbors better than I. Some people are best
left "in the dark" if you know what I mean. People with a more
progressive attitude can be acclaimated to the fact the
Frankenstein is alive and well, and living next door.

The best bet if you are going to be firing in the open is to be
open about it. Approach those neigbors who might be disturbed and
explain what they will be seeing. Assure them there is no cause
for alarm. Ask them to contact you if they are concerned or
disturbed. Be pleasant!
