I would feel MUCH more comfortable with Rohn 45 or 55.
N4AR had a 40/20M combination on Rohn 25 many years
ago and noticed the galvanizing began to crack on the top
section from all the twisting due to the high torque load.
Is this the antenna with 40M? If so, 80 to 100 ft might be
a better choice, with a high band antenna (10-20M) at 40 ft.
As you have heard me say many times, you need BOTH
high and low antennas for the high bands. On 40M,
80 to 100 ft is a killer height for the evenings. At sunrise,
it is nice to have a really high 40M antenna (150 to 200 ft)
for the SSW LP to central Asia and SKEW path to SE Asia.
