They are closed on the ends, and don't seem to unscrew easily. Trying to
figure out what the purpose is, and did not have tools with me to take off
the plate to investigate further.
That's what the female connectors look like, but what would be the purpose of
the closed "cover" screwed onto them? And why so many?
The short story here is that my tenants just moved out of the house, and there
connectors are now here, which I don't recognize as being there before. I
thought they might have had satellite TV, but can't understand why they'd
need more than one.
Cheers,

Please could you provide a close up picture of the connectors.
I assume that you are in US or at least using US style mains plug
These connectors look like some sort of cable TV but we need more to go on:
dimensions, type of thread.... or are they some sort of pipes????

I will be back there on Tuesday, so I'll get a better photo then. Also
planning to take them apart to see if I can figure out more about them.
Thanks,
-Neil.

Dish Network has a multiple satellite system where a slightly more
elliptical dish is used to receive the signals from two satellites,
which are relatively close. Two cables are required to bring the
signal from the "dual LNB" satellite dish to the satellite receiver.
The third connector might be to pipe the decoded satellite signal to a
TV in another room. They either just split the signal going from the
satellite decoder to the TV or they have special dual receiver
satellite boxes so that the two TVs can watch different programming.
(UHF remote and all.)
They make caps to go on the F-connectors. I'm not actually sure what
they consist of, though. Perhaps a matched load? Is that 50 Ohms on
standard coax? Maybe they just act as fancy dust/humidity covers.
Often times people will use a wrench on the connectors to really
tighten them down for some reason.
I couldn't explain why they used three separate holes and wall plates,
though. Nor, can I explain why one is at a different orientation.
They do make multiple-gang F-connector wall plates, but perhaps they
didn't have them at Home Depot or the installer was lazy.

Actually if they are for certain DBS systems then more then one
connector makes perfect sense.
Most newer sat receivers for DISH(US)/ExpressVu(Canada) are dual tuner,
because of the way things are done you need a feed from the dish (or
multiswitch) for EACH tuner, even if both tuners are in one box (meaning
one box has two connectors).
Things can get even more interesting if you have a dish hitting multiple
birds and you're cheaping out on the switches.
Another likely reason is someone who has sat and cable TV (i.e. hacking
the sat and paying for the cable TV), or someone who wants SAT and a
cable modem for internet access.
I recently visited a house and saw something similar, every room had two
cable outlets, sometimes more (in different locations).

If they come out at other places in the house then there is a Y splitter
somewhere. The covers prevent an unloaded Y arm from being unmatched.
The covers should contain a matching resistor each.

You need one per dish (one per LNB is using offset LNBs on the same
dish). Many people would use 2 dishes plus a local antenna.
Interesting you mention "roof" -- I'll have to check around to see if there is
some wire running into the house.

They sort of look like F-connectors like used for cable TV and such. The
closed-off connectors screwed onto two of them *might* be terminators -
these are usually just a 75R carbon resistor soldered or crimped into a
standard male connector. (One lead of the resistor is the male connection.)
