HI Robert,
I have an Alpha-Delta DX-a twin sloper that works great on 160, 80,
and 40m. I have a 55' tower and the sloper is attached to the top. I
have a ground wire runnng form the mast pipe to three ground rods at
the base of the tower plus one at the bottom of the 6.5 ' hole (it's a
self supporting HDX-555 crank up)
The 80m leg is 67 feet and the combination of 40 and 160 is roughly 60'
Check it out on the A-D sight. It is a great preformer on all bands.
