Warning, don't fry your modem.
Yes, there is DC power supplied by the modem going through the coax to power the radio on the dish. Under certain situations the modem can be damaged if the power is shorted out. There are protections built in but they don't always work.
Also one reason we say to power down the modem from the wall receptacle, not the plug on the back of the modem.

Just an interesting thought to consider. Which is more important? Ingress protection, or maintaining transmit power and throughput without any significant loss or gain (depending on how you look at it)
The connector in question was likely not weather sealed properly, as well.
obviously so, however the point is that a type F connector (while not IP rated per se) are standard IP64 and applying a dielectric is poor practice...but one is left to consider: do we care more about a cable being submersible, or about ensuring an impedence match.
