The folding dish is a lightweight parabolic dish that can be used for ham radio or radio astronomy. The dish uses spaceage RF reflective fabric and 16 carefully stressed fiberglass ribs. This dish is available as a 1.0m (FD3) , 1.8m (FD6) and 2.4m (FD8) version. Feeds for 902 MHz, 1296 MHz, 1420 MHz and 2304 MHz are available. The is folding dish has good performance to 2.5 GHz.
A dual linear polarization patch feed is available for use with the folding dish. The feed is supported on a fiberglass monopole support and is detachable. The patch feed attaches to its support with a simple twist and click. An optional low loss quadrature hybrid combiner is used with to this feed and generate circular polarized signals. Each feed has a VSWR better than 1.25:1
The SL-1 is a lightweight Az / El position designed for the FD6 and FD8 folding dishes. It can also be used for smaller yagis.

The SDD3 Dual Axis Slew Drive was designed for moving large Yagi and Dish antennas with 0.1 deg. resolution. You can reliably track the moon, sun, stars and LEO satellites. Powerful DC motors are geared down 570:1 to provide lots of antenna moving power. Compatible with many popular antenna controllers.
This heavy duty pole mount is made with SCH40 aluminum. Fits on a 3.25" (or smaller) pole and clamps with M10 steel bolts. The adjustable top plate has pre-drilled holes to hold the SDD3 slew drive. This pole mount can also be used to hold a telescope or other sky-looking devices.
