Good morning!
Has anyone modeled the 1/4 slopers? Perhaps the Alpha Delta DXA?

The pattern and performance of a 1/4 wave sloper is extremely dependent on
the tower and what is on the tower, the guy lines (if uninsulated), and even
how the tower is grounded.
There are very common cases where it won't
IMHO a wire 1/4 wave length long wire should preferably be electrically
connected to the tower and fed from the bottom of the slope against a
good ground system. AM stations that have done this in emergencies
report good results.In fact some consulting engineers were so impressed

Herb,
That depends on the height of the tower. I have two sloping wires on
opposite
Jim.You hit on a good point with a 1/4 sloper that it should be some
distance, in your case 5 feet, from the tower at the top or high voltage
end. Having the top right at the tower seems to deteriorate the
performance overall as many who have tried this seem to underscore.
