The Olde Antenna Lab may still make those to order. Those were his specialty for many years.

Are there any commercially available skew planar or “cloverleaf” antennas available for 2 Meters/432? These have become commonplace for drone operations at 2.4 and 5.8 GHz because they offer circular polarization. This makes control of the aircraft more reliable as it moves through space with changing antenna orientation. Previously, omnidirectional antennas similar to our “rubber ducks” were the norm.
Skew planar antennas seem to offer a good option for satellite operations, especially portable. But availability is always an issue.
