[TowerTalk] Laying out radials around a stone fence

[Don Moman VE6JY]

An experienced local MW broadcast engineer and low band ham, VE6LO now SK,
did some experiments with radials on a 160m vertical he had with a yard
that also had obstacles.  Using a RF current meter (similar to the MFJ 854
I expect) he came to the conclusion that if a radial had to be bent to go
around an obstacle, you might as well not bother - as he found very little
RF continued past the bend.
