What is 009 about?

## 2 axis mount for VSRT tests An inexpensive (~$150) azimuth/elevation mount for a pair of 18"×21" offset direct TV parabolic dishes can be put together using a pair of SG2100 DiSeqC motors (which support 1.2 Goto×function). The SG2100 is rated for a single dish up to 1.2 m but may be able to reliably point 2 smaller dishes whose combined area is less than the larger single. In a strong wind the moment on the elevation drive is less than it would be for the larger dish but the larger center force offset for the azimuth drive could reduce its life and tests will be needed to see if the design I propose is reliable.
