First of all, 10 to 13 feet guy wire length, before adding the first
insulator, would be absolutely the worst thing to do if you have a 15
meter antenna in the vicinity. Think about it - you have created a
resonant 1/2 wavelength 15 meter element consisting of two 1/4
wavelength wires, interconnected by the tower section.

I recently wrote an article, published in the Novemeber/December 2015
NCJ, on the subject of modeling and choosing guy wire lengths. It
partially debunked the old table in the ARRL Antenna Book of "good" guy
wire lengths.
