Careful, when you use pipe that way you don't have any vertical support
for your cables in the pipe. The full length of the cable hangs from
whatever support you have at the top, and depending on the height of
your tower, there can be an awful lot of weight hanging from that top
anchorage. You likely will end up with your cables stretching out over
