A work in progress:

New Periscope antenna system for 10 GHz

During construction

and up on the 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!

Now with new tilt indicator on flyswatter

With tilt sensor installed

Tilt readout

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

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:
10 GHz Snow scatter recordings from January VHF contest:
Station #1
Station #2
Station #3
10 GHz Rain scatter recordings from 9 March 1997
Let me know how they sound!
DSP guys - can you find a way to improve copy?
