I've taped them in the past, but they look lousy when the tower isn't all
the way up, as all of the cable is still up in the air. (I frequently have
my tower lower to sleep better during frequent winds where I live in
Arizona, near some mountains.)
This time, on my 89' US Tower, I let them hang as Steve says, but I was
worried about all of the weight hanging at a sharp right angle from the top
stand-off. I taped the cables (2 coax, 1 rotor, and 1 remote switch) to the
top stand-off with both the thick pipe wrapping tape from Home Depot and 3M
33+ (didn't have 88). I then used an electrical PVC (the gray stiff) PVC
"sweep" piece. That's the gradual bend type; I used a 90 degree bend. I
forget the size (1.5"??) that went through the UST coax stand-off and taped
it in place with lots of the thick tape. This way the coax doesn't get
deformed, I hope, from the weight and Arizona temperatures.
BTW, I've found the adhesive on the thick tape doesn't last well, so I
usually wrap it with 33+.

Actually I prefer to secure them at the top coax arm and then let them
run thru the others without being secured. It's very time consuming to tape
the cables, run the tower up and see if it's right (it'll always be too long
or too short), run it down, make an adjustment, repeat many times.
When the tower is lowered, the cables just lay on the ground until you
raise it.
