Hello Jim, Coilers,
What I've found to be effective in my garage/shop is a large plate of
sheet steel hung on chains from the roof trusses so that it's just a
bit below the opener. My plate is about 3 feet by 2 feet and I ran
a round wire from it to the main RF ground for the coil. Although I
have the coil directly below the plate, I've never had a strike to
it even though the streamers are much longer than the distance from
the toroid to the plate. They seem to want to go horizontally out
from the toroid rather than up. To date, no problems with either
the opener itself or the radio control.
