I use 1/4" copper tubing coil (about 8 turns?) accross the coax between the
ground connection and bottom of the (mobile) vertical. Use soldered and large
surface area connections with hose clamps. You can use larger diameter tubing
and find minimum turns for 50 ohm match. It also provides DC ground path in
case lightning chose to find the midget :-)
I think that is about as efficient match as one can get. I run about 800W and
no signs of fire or peeling paint.
