Thank You for the replys. I added radials and the impedence is coming down
as it should. Oh my, I had it backwords! I thought the impedence should
start low and increase with radials... while the opposite is true. I once
better... but I've have been struggling with memory problems related to Lyme
disease. Thanks for your patience.
I got down 6 radials before dark and the impedence on the 40-meter vertical
is now down to 60 ohms. I'll add more tomorrow.
Hope to work you in the IARU this weekend!

With no radials, your quarter wave vertical should have 75 to 100 ohm
feedpoint impedance. The impedance should come down steadily as you add
It should get down near 50 ohms after you have 15 to 20 radials installed.
It should approach 40 ohms after you have 30 to 40 radials installed.
The exact length of the radials laid on the ground is of no importance. 30
to 50 feet is a good choice for 40 meters.
