NEC shows this for a theoretically perfect 1/4-wave vertical

I need to correct the values I posted earlier. I mis-read the larger
table I had constructed, which was apparent when calculating the
values for a ~200 degree vertical.

I don't work the low bands enough , but I would have thought someone would
have just gave some prctical experiance instead of all the NEC stuff. Not
many hams are going to put up a 60 some foot vertical and the required
ground system for 80 meters.

Could not someone say that with horizontal dipoles about 30 feet up (or
whatever is being used) you may get so many miles ground wave and during
the day so many miles skywave and so many more at night ?

NEC and other programs are fine for predicting the coverage, but it does not
take into account all the variatables that can be answered by the
experiance of actual operations.
