Laying a cable under a patio

This coming weekend I've got to re-lay a patio which was taken up when we did the conservatory install. But I need to run the TV Ariel into the conservatory. The only problem I have is that the Ariel needs to go under the patio. What can I put the cable into to stop it being damaged. At the moment I'm favouring some copper water pipe. It doesn't really need to be that large just thick enough to fit a Ariel cable in.
Thanks

Hello,
You can use anything, from copper pipe to a piece of hose pipe, or that thin plastic water pipe stuff from B&Q, just seal the ends up by putting a few layers of self amalgamating tape over them and the cable. Simple as that!

Copper pipe might not be a good idea for a couple of reasons:
1) The TV aerial lead is designed to work at a given capacitance, reactance, and resistance. Shoving it into a copper tube is very likely to change its operational characteristics. Whether or not this affects the TV signal I can't say, but it would be worth trying it out before you bury the cable in the conduit.
2) I would have thought it increased the likelihood of lightning damage. If a lightning strike came to earth anywhere in the vicinity of the property (it doesn't have to hit directly) then intuition tells me that the copper pipework might pick up a lot of power. That power would transfer to the aerial lead, and the aerial lead is connected to the TV set. The TV set goes boom!
(why am I sat here singing to myself "the thigh bone is connected to the, neck bone. The neck bone is connected to the, ankle bone...", ?)
You might be better using a plastic conduit.
