Need help: coax feed to a wire antenna

[Treehouse SWL]

OK - simple technical question. After my puppy dug up my previous longwire feed line, I've buried a coaxial cable inside underground PVC pipe along the outside of my backyard fence. She can't get to it there. The feed into the single balun is wire, not coax, so I need a simple and somewhat weatherproof way to connect the wire and the coax to each other.

Any ideas? I'm a writer in my day job, not an engineer, so I need to keep it simple for my abilities!

If you want to go on the "cheap", make the connection in a plastic box of some sort,   sealing the holes where you ran the wire and coax into the box with a good sealant.   For the actual wire connection between the wire and the coax what is now safe,  use Gardner-Bender's liquid tape.   A few coats would natually be better than one.   Other options exist like using shrink tubing with diaelctric grease underneath as well. You may have better luck using a good coax to wire connector instead of directly wiring the connections...but...that is up to you.
