Topband: Best 160 antenna

Have there been any professional studies done on the efficiency of elevated radials?

One would think the broadcast industry would be interested in a few elevated radials instead of burying all that expensive copper. They could use the Aluminium conductor steel-reinforced cable favored by the power companies.

I read N6LF's paper and I recall he emphasized the radials should be tuned? What are the effect of changes in foliage around the radials ground moisture content when it rains or snows.

I tried elevated radials when I installed my Inverted L but found it problematic supporting four quarter wavelength radials in the yard. Also, the XYL doesn't mind some wires strung across the tree tops but would object to low wires strung about the yard.

I ended up placing radials in the ground since most of that part of the yard is wooded. They get buried under the undergrowth and leaves.
