I used to use a similar method on 80 meters.  
Why not feed it (them) at the top?

That's exactly what I'm doing -- my tower is 115 ft with roughly 7 ft of
mast above it and a 3-el SteppIR. I have sloping wires on two opposite
sides, supported from the tower just below the rotator with a 10 ft section
of 4-in PVC conduit. Each wire has its own set of 4 radials elevated about
18 ft. The tower, which is grounded, has a dozen or so radials laying on the

With this configuration, the tower will act as a reflector, yielding about 6
dB front to back. How much GAIN you get will depend on your radial system
and the quality of your soil. I started with radials elevated only a few
feet, and gain was poor. On the advice of N6BT, I raised them and gain
