Jim, Why not just shunt feed the tower? 70 feet with that beam for top-loading is a good height for 160. If it will be a guyed tower these would need to be insulated, and run all cabling from the bottom and inside the tower whether guyed or self-supporting.
Based on some discussion on the reflector a few months ago, the tower would best be sited at the center point of the existing radial field. Offsetting it along one of the radials would be like using only one radial. 73/Jon AA1K www.aa1k.us -----Original Message----- From: Topband [mailto:[email protected]] On Behalf Of Jim Miller Sent: Monday, May 16, 2016 7:41 PM To: [email protected] Subject: Topband: Inverted L off tower? 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?
