what were the rough lengths of your dipoles?
for me to work it out in meters, I use the formula 300 divided by f.
also, did you use any baluns? I want to make my own but not quite sure
how to accomplish that just yet, I need to make sure the toroid I use is
the right rating and size. thanks in advance.

to impart this pearl of wisdom:
> Hi Shaun,
