Tried 2 tv masts today 20ft total.
Antenna is A NW antennas L-160 loaded DIpole, fairly heavy.
Bent them suckers right over.
Need that tree next door back
==============
You might not need that tree,but instead stiffen the 2 TV masts,by
fitting (in the middle of each mast) 2 outriggers perpendicular to the
mast in the same vertical plane in line with the antenna.
You then connect the free ends of the outriggers with both top and
bottom of the mast using steel wire + tensioners.
