Thank you for the recommendations, tfoote. I intend for the loader to be in a fixed position during operation (such that the antennas are pointing straight up). I did think about putting the antennas on the extrusion but I want the increased precision of having them farther forward, plus it gets them away from the cameras and antennas I'll have on the extrusion. The grill guard wobbles a lot and does not offer the spread I need. (It will also be shadowed when the loader is lifted. I'll have a fertilizer tank up front.) I only use GPS - no odometry or IMU. That's part of the problem I bump into whenever I try to use ROS tools instead of the code I've written. --- [Visit Topic](https://discourse.ros.org/t/tractobots-my-attempts-at-field-robots/1486/10) or reply to this email to respond.
