It may be another thread, but some reality needs to go into your decision.
Just because a nearby antenna is non-resonant does not mean that it will not
interact with other antennas.
Every ARRL Antenna Book written in the past 30 years has a figure showing
"ungrounded guy wire lengths to avoid". It shows 26 feet to be a "magic" length
for 10, 15 and 20 meters. Now take your favorite modeling software and put this
"magic" length within a few feet of a 10, 15 or 20 meter yagi. Major pattern
distortion.
