and up on the W1GHZ tower.

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!

The periscope antenna worked great for rainscatter during the June VHF Contest. I worked four grids on 10 GHz, best DX >130 miles, during heavy rain.
