Jim,
On your sloper and the 2x segments idea for wider bandwidth, have you
thought about just running 2 separate sloper wires with one slightly
longer than the other in a fan arrangement? You could trim those lengths
from ground level to get the resonances where you wanted them. Hold
those apart a very short distance at the ground end, sort of like the
fan dipole antenna. That would eliminate any relay at the tower top.
As to receive antennas, It might be worth putting up a LoG antenna (Loop
on Ground - https://www.kk5jy.net/LoG/) with 30-feet per side
dimensions. I have one and it can work wonders sometimes. That's right
on the grass and after a few weeks it just disappears. I also use a
10-foot by 30-foot flag antenna, and it's fed at the bottom corner and
un-terminated. I phase that against the LoG or another flag to null down
noise and even atmospheric noise can be nulled as long as it is not all
coming from many directions or many wave angles.
A few thoughts for you...
