comment Can I use conduit to ground an antenna?
@ThreePhaseEel Not necessarily. The conduit may be feeding the meter pan, then the service panel could be fed by a cable or nonmetallic conduit.

comment 4 way switch controls two outlets and one overhead light oppositely
You should include some photos, and a better description of the wiring. As it stands, there's probably not enough detail for anybody to answer your question.

If it all worked, why did you change it?

comment Can I use conduit to ground an antenna?
@ThreePhaseEel Sure, but like I said. If that conduit is used, it has to be bonded to the electrical system's grounding electrode (810.21 (j)).

You can only use the conduit as a grounding electrode, if you bond the conduit to the grounding electrode of the electrical system, or if it already is bonded. there's no shortcuts, if you want to do it right.

Sorry, I thought the conduit you were using was the conduit that the coaxial cable was running through (from shed to house). It sounds like you're going to have to drive a ground rod at the shed, and bond it back to the grounding electrode at the house. The diagrams in the answer I linked to will help you.
