What signal is carried by Cable TV? Is it VHF, UHF, anti-protons
(lol)?

Where I'm living now, I cannot possibly throw a cable to my room, so I
am considering
building a transmitter/receiver of CATV, if that's even possible
economically for domestic use.

Does anyone know where I can find such circuits?

The first two.

If you mean you want to broadcast CATV to your rabbit ears and loop,
don't. The mid-band is shared with aviation and the CATV copany does
leakage checks. You'll be interfering with peoples off air reception
(which is on a different channel line up) and ghosting the CATV
signal of others who may have leakage (ingress.)

The line amps at home depot and such give varying degrees of signal
quality and the ones outside on the line start at $700 or so and require a special power supply. *Why* can't you run a cable to your room.

You'll be interfering with peoples off air reception (which is on a different channel line up) and ghosting the CATV signal of others who may have leakage (ingress.) if you have line of sight maybe you could use a modulated laser beam to avoid interference, then you just have to worry about blinding everyone who looks in the wrong direction, or isue lots of safety glasses. or maybe you cld put the receiver at the far end and just transmit the station you want, you can get video senders wich use a gighz or so, asuming your remote has long range. just have to hope no one else nearby has the same idea..

why do i have visions of it being in a tree house ?? (maybe its the mention
of rabbits).

ive often wondered what i wld see if i stuck a scope on the end of my
cabletv/modem line, but scared of breaking it, as its NTL it might be a bit
fragile and cld be ages before it got fixed...

im also interested in a pc card that wld receive chanels direct from the
cable even if its just the unencrypted ones, atm my pc vcr (ATI AIW) is
limited cos it cant change the chanel on the receiver box, although there
was a thread on pc controled ir remotes ...
