Picture of the Current Design For Patch Antenna Tracker

• ***NOTE*** current Antenna Tracker is designed only for Patch Antenna. Currently not compatible with Yagi Antennas.

Potential Changes

• Move the battery and receiver mounting positions from their current positions to the side panels.

  • Pros: Less material needed. More space for other electrical components.

  • Cons: Not balanced around center of mass.

  • Any thoughts?

Previous Design of Antenna Tracker for Yagi Antennas

• As per discussion with Nathan Green, previous CAD and design has been lost

• Video of old Antenna Tracker for the Yagi Antennas: https://www.facebook.com/UWaterlooWARG/videos/tracking-antenna-first-testa-little-jumpy-but-a-great-first-test-signal-reliabil/661647633941945

• Note that the parts utilized to create the Yagi Antenna Tracker were obtained from ServoCity: https://www.servocity.com/

Questions

Arjun Mandair

• Am I essentially making two separate Antenna Trackers for the Yagi antennas and the Patch antenna? Or am I making one Antenna tracker compatible with both?

• Anthony Luo suggested a “crossbow” like configuration where there's a flat plate above the drive servo so that the antenna can be centered . Are you referring to a flat plate similar to the one below?

• Are the current servo positions ideal knowing new constraints?

• Anthony Luo asked if the current antenna tracker is compatible with HS311 servos. Should the designs be compatible with HS311 servos?
