I would look in "Spy" stores for transmitters. I'm sure anything that
transmits more than a few meters would be limited in some way by the FCC
(in the US). Also, you have to take into consideration how the pipe or
tunnel will affect the signal.

Yes - check out Gantenbrink's robot which was used to explore shafts
inside the Giza pyramid. This one cost a lot of money though! It had to
travel about 200 feet with only about 8 inch cross-section. You might
get some ideas for the expanding structure and treads though.
It also had a colour camera with zoom on it and a laser pointer to shine
into cracks.
Anyone know how of a small legal video transmitter of sensible price to
avoid a cable? The actual camera can be CCD a few centimetres square so
that is not a problem.
