Here is the correct link, I hope....
That link shows weaker signals from all stations. Using the same coordinates indicates a problem with a strong FM station WFAF at -27.2 dbm. Yet the Clearstream 4 antenna that you have has very little sensitivity on FM.

That would lead me to conclude that there is a fault in something. The coax could be shorted or open, the balun could be defective, the preamp might be connected improperly, the preamp and/or power supply might be bad out of the box, or the 120 volt outlet with the preamp power supply is dead.

Occasionally the antenna can be aimed wrong, not because you didn't sight it properly with the compass, but some inexperienced installers have misunderstood which is the front of a particular antenna and which is the back.
