Yes, a single strip holds up rather well... up to a year between changings. $1.19 as best as I can recall and it comes in a rainbow of colors. Yes, there are a few tricks.
1. Best results come when you work with the tape at temps above 70 degrees.
2. Flip the bike upside down to do the work so that gravity works for you, not against you.
3. Clean the tube with a mild polishing compound then wipe it down with isopropyl alcohol to remove any of the fillers and polish left over from the polishing compound.
4. If you have paired wires make sure you straighen out any twists so that they'll both lay flat down the length of the tube.
5. To keep the signal wire centered as you put the tape down, temporarily tape-down or zip-tie the wire at either end of the tube. Make sure you don't have the wires pulled too tight coming in from the stokers handlebar or running out to the fork or stays end to keep them from pulling away from the frame once the zip-ties are removed.
6. Pull off a little more tape for the length required and then let it hang there for about 20 seconds so that it "shrinks bacK" to it's static length. Make sure it's about 2" longer than it needs to be then cut it, being sure to handle it by the ends that will eventually be cut off.
7. Carefully lay your strip of tape down on top of the signal wire, but not yet touching the tube: don't stretch the tape as you lay it down.
8. Run your thumbnail or a fingernail down one side of the wire to "tuck" the tape down tight against the side of the wire and tube: you want the tape to be tight against the wire and tube without any air pockets.
9. Run your thumbnail or a fingernail down the other side of the wire to get that side tucked in tight.
10. Trim off the extra tape at either end of the tube and press down the remaining ends, making sure that there aren't any openings or gaps where the signal wire exits out from under the tape.
That should do it for some time to come. It's riding in the rain, washing, and the like that will eventually cause the tape to lift at either end and you'll have lots of fair warning as to when you'll need to trim off the cruddy ends and put down some fresh tape and/or if you choose, to replace the entire length of tape. You'll want to use a rag coated with WD40 to remove the residual tape adhesive before repeating the installation process.
Debbie now uses a wireless Polar S720i but I still use tape to attach my HAC4's cadence signal wire to the down tube of our travel tandem. The downtube installation takes a real beating with all the dirt and grime being kicked up by the front wheel and I replace ends of the tape about once every 2,000 miles or so.
