Radio spelunking reception

[HANKMARS]

What are my chances of receiving clean video signals from a radio transmitter ~ 500ft directly below me in an eight inch diameter hole. I am also curious as too the added situation of the radio trans being submersed in ~ 200ft of water, in the same size hole.

Another issue that may affect radio comm is the fact that an inch and a quarter steel pipe will be sharing this hole.

Alrighty then. We'll sideline that idea for the moment.

Drop a cable or fiber & run the RF over the cable.
