[TowerTalk] Slopers, half slopers, (using the tower)

[Doug Renwick]

Roger,

I use two half slopers on 160M with the feed point at 100 ft and under a
number of yagis.  One slopes east and the other west and I do have gain
in the direction of the slope. More than two half slopers showed no
benefit here but you may have different results.
