From Parts Express, $1.70 for a Neutrik RCA, $2.45 for a 1/4” TRS plug (or $2.33 for an XLR), $0.60/ft. for the cable. Plus shipping. Do you have a soldering iron?
Yes, I have a soldering iron and most of the basics (electrical tape etc).

At the CATV frequencies, it's best to buy off the shelf.
Even if you attack it at the audio level (i.e. transformers after or before the BFD), it has to be done to pass the low frequency signal of a sub without attenuation. A transformer that can pass 10Hz would be the Jensen variety you mentioned earlier. Pricy though..
Would this apply to the approach Wayne is talking about with the custom cable, and I'd have to worry about whether the sub frequencies were getting mucked with? Or is the custom cable/connector approach just a matter of isolating the ground that doesn't really make any changes to the frequencies itself (my understanding)?

Thanks!
