My QTH in central Delaware is about 12 acres with most of it a "young" forest of loblolly pines, oak and maple that top out around 80-90 feet tall. Prior to 1978 or so most of this was cleared farmla

Jaan, Before replacing the guys, you might consider trying a gamma match at the bottom end of one of the top guy wires to load the tower and guys as-is. I did something similar on a sailboat for 80 m
