Robert’s four-bar linkage 3

It is developed from the mechanism shown at: https://youtu.be/0nS8aTPnUlM
Dimensions:
- Distance between the stationary points = 2a
- Length of yellow bar = b, such that b is larger than 2a/3
- Side lengths of blue triangle CDE: a, b, b
- Side lengths of green triangle FAD: b, b^2/a, b^2/a
- Side lengths of red triangle CGH: 2a, 2b, 2b
- Length of orange bar = b^2/a
The blue, green, and red triangles are similar.
If point C moves from A to B and vice versa, then the red T-link moves rectilinearly in a straight (approximately).
The inventor of this linkage is Arglin Kampling:

Thanks to the inventor for providing me the linkage dimensions.
