If I had that kind of available tower height and the flexibility to
place them that you do, I'd make the 2nd tower also 150 feet tall and
position it such that a rope between it and the 1st tower pointed to
Europe, with enough distance between the two towers that I could string
Inverted-V elements for either 80m or 160m to make a 3-element wire Yagi
hung from the rope. The coax to the driven element could be run back
along the rope to one of the towers.

About 20 years ago, after erecting a 150 foot tower (Rohn 45G equivalent), I
was inspired to continue toward a multi-multi station. I began to look for
and purchase other towers and antennas. So far, I have 320 feet of Rohn 55G
and 56 feet of Rohn HDBX. These sections have been stacked under an oak
tree for many years. I also acquired about 10,000 feet of used Phillystran,
and about 2000 feet of new old stock Andrew LDF50A coax, the longest piece
being 500 feet. Plans to erect got halted by heart arterial bypass surgery.
Well, 13 years after surgery I am still here, and in excellent shape. So, I
am thinking of putting up at least one more tower, and making do with a
multi-two station. The new tower may be a 200 footer, but I am also
thinking of a 120 footer, which would be easier to maintain, and may be
ideal to place my M2 40 meter 4el antenna (40M4LLDD). I have 16 acres, so
placement can be flexible. The existing tower is less than 30 feet from the
shack. I am thinking the second tower should be no more than 200 feet to
cut down on signal loss. I am wondering if this is a practical limit, and
how far from the existing tower it should be located. Suggestions and
recommendations are welcome. Thanks.
