One of my friends is thinking about installing a 70 ft. tower with a
2-element shortened 40M yagi. He is thinking about installing the new tower
in a location where he now has a vertical used for 80M and 160M (i.e - the
existing radials will terminate at or close to the base of the new tower).
He is planning to relocate the 80M vertical to another location with other
radials. He would like to support an inverted L for 160M off of the new
tower, using the existing radials. His question is, how far must the
vertical leg of the inverted L be spaced from the new tower, with a view to
keeping it close enough to use the existing radials?
Thanks
