Topband: How good is good enough

[Lee STRAHAN]

And don't forget to discharge the element to ground before connecting to your measuring device. Static is NOT your friend in this case.

If that were all I could add, I'd switch them to 40 35' radials.

The R component of my inverted L on around 1840 is 11 ohms.  X is around 20.  That's with 101 radials.  I look for a R of at least 15 ohms where X is minimal on an analyzer sweep.  At that point the ground system is getting good.  The vertical part of the L should be
at least 50 feet.    Just ground the analyzer and put the vertical
element right into it.
