The fact it won't pass power in the reverse direction makes it useless for my current build, though.

I am confused by these statements. No protector works by blocking or stoping a surge. In fact, that blocking or stopping is impossible. The protector should work in either direction. To a signal, a protector should look just like a coax wire.
View these spec numbers. Is your existing 'problem' similar to these specs?

View the wire from antenna mast to ground. That is also what any protector does. No protector works by absorbing or blocking a surge (which is why protectors adjacent to appliances also claim no such protection). A protector only does what that wire does. Obviously, if the coax center conductor is earthed, then no signals will flow. So a protector connects that center conductor to earth - and still have TV signals.
Some protectors make that connection with significant losses. Others do it with minimal losses. 'Lower loss' protectors also are rated at higher frequencies - ie 3 Ghz and 7 Ghz.
But again, no protector does protection. The connection to and quality of earth ground determines protection.
