Please forgive my skepticism of the old antenna and coax, but they are unknown quantities. Rather than buying a second FM-trap, I would buy a new section of RG-6 with connectors, long enough to replace the run up to the antenna. I would not permanently install it necessarily, I would use it to test with the indoor antenna outside, on the roof if necessary. The goal would be to determine if you are able to see any signal from KGO.

The RCA ANT121 dipole rods should be roughly 30" tip to tip for channel 7. The dipole rods should be perpendicular to the line toward KGO's transmitter. You can test with and with out the trap.
