A 1750 meter signal into a vertical antenna in the trees will not work
any better than a resistor on your bench. Put a TX loop up and you will
get a signal out. When my Lowfer rig was on the air at 700 milliwatts
output into a Ashlock loop, it could be heard at 162 miles in regular CW
day and night. On 1750m loops work in the trees, verticals don't at all.
