Arrow Antenna adapter for Telescope mount

Telescope Go-To rotators are an excellent, cost-effective solution for automated amateur radio satellite (AMSAT) tracking. However, mounting a handheld antenna where a telescope tube usually sits requires a custom solution.

This adapter bridges that gap, specifically designed to mount an Arrow Antenna (Model 146/437-10WBP) to a NexStar GT rotator.

Key Features:

• Dual-Shell Design: Features an inner and outer shell "bearing" system.
• Axial Rotation: Allows you to rotate the antenna axially to easily adjust for signal polarity during a pass.
• Universal Potential: While designed for the Arrow/NexStar combo, the design can be modified for other boom-style antennas and mounts.

Open Source: The original CAD is public on OnShape for those who wish to remix or tweak dimensions.
