Topband: Quarter wave sloper ?

[Rick Kunath]

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...
