Just *how* badly does continuously grounded guys mess up the antenna
patterns on 20-15-10 meters?? I seem to recall an article in QST or some
other publication about 10 years back that stated that most installations
will suffer only marginal degradation... on the order of 1/4 db or so. Did I
misread this or have there been more recent studies?
