You don't know how much I really want a lakeside/riverside house. Would love to have a constant supply of watery microlife.

I feel like there's a joke here I'm missing, but if not then yes of course! There is some leakage but the basement is unfinished and it's a single-level house so the pipes are easy to access.

One interesting feature of the house is that it has a boiler furnace instead of forced air, so there are no ducts.

Another interesting feature was the whole house TV/FM antenna system I still don't fully understand. These wall jacks in every room with these little doohickeys plugged in to them, and a giant metal antenna on the roof.

Not so much a joke, more of a loooooong ago callback

I think those are really old school telephone jacks.

*checks*

Nope, the ones I'm thinking of were four prong.

It looks like maybe what these people are talking about here.

I have a very vague recollection that most roof mounted FM antennas can pick up digital TV signal pretty well, so you might want to just try that and see if it works. I don't know much about this stuff, though, overall, but sometimes, I get lucky just trying stuff like that.

(The weird part is that I can't see where you'd even put a lead in to those. In that little slot on the bottom, and twist it around the screw maybe?)

Edit: It just occurs to me that there was a major reallocation of the broadcast spectrum like a year or two ago, so that stuff I read about getting DTV signal over FM antennas might be outdated again.

It looks like the house is wired with balanced (twin-lead) wiring for distributing the antenna signal. The wiring in the walls is most likely flat twin 300-ohm cable. To connect to modern gear, which uses unbalanced (co-ax) 75-ohm cable and connectors, you need a balun. A balun is an impedance matching device - often a small transformer - but they can also just be stubs of cable cut to a specific length to suit the working frequency, and either short-circuited or open at the end of the stub depending on the length.

Lots of different designs of 300-ohm wall plates were used: often they just had two screw heads, and you hooked up a twin-lead flat cable with spade connectors to them.

It looks like yours use a three pin plug, but it's likely that only two of the pins are actually connected. The third pin, if it is connected, is likely an earth.

Nothing wrong with balanced feeder line: the common designs of TV antennas (yagis) are inherently balanced, and either have a balun built in to them, or just waste some of the signal by connecting directly to unbalanced co-ax cable. So the old-fashioned system of distributing the signal around houses or apartments made perfect sense, and in many ways was better than the modern way of using co-ax.

Small neat 300-ohm balanced to 75-ohm unbalanced baluns are still very widely used, commonly available, and very cheap (look on eBay) but I don't know where you can buy the particular plugs that fit your existing wall plates.

It's interesting that ethernet wiring has gone in the opposite direction. Years ago we used unbalanced co-ax, but now it's all balanced twisted pair: cat 6, 7, 8, ...
