The flyswatter reflector, which rotates and tilts, is fed by a dish on the ground
directly under it.
Dick, K2RIW, has been talking about periscope antennas for so long that I had
to put one up and show him how to do it!
Now with new tilt indicator on flyswatter
With tilt sensor installed

The tilt indicator is a Wineguard "Digital Magic" Elevation Sensing Unit. I got it

The periscope antenna worked great for rainscatter during the June 1998 VHF
Contest. I worked four grids on 10 GHz, best DX >130 miles, during heavy
rain.
Here are some new sound clips of AF1T on CW and SSB.
WA1MBA has written a good
explanation of rainscatter.
The following contacts were
made with my dish pointed straight up through a skylight, into light snow
in January, heavy rain in March:
