Please note that KAXT transmits from Mt Allison which overlooks Milpitas to your south-east. KTSF transmits from Mt San Bruno, several miles south of San Francisco.
Please verify that the C4 is aimed properly for the desired station. Also, please note that the directions to the two towers form nearly a right angle. The C4 has a major null at the 90° points (due left and right of bore-site), same as any panel or loop antenna or even a dipole. That means it's close to blind at those angles. The C4 is moderately directional, so don't assume it's going to receive stations from widely varying angles. A reception pattern is printed on the back of the retail black box.
