It uses a specified carrier wave modulated by a combination of two different audio tones, one for the row and the other for the column. They come in 3x3, 3x4, 4x3, and 4x4 configurations. If used for activation of a specific circuit, it would be able to access 12 different devices.
It could also use several encryption methods, but that would be overkill for a detonator. No one would be expecting a signal, so no one would be looking to decrypt any signal that came across the airwaves. Sort of overkill to my mind.
The ladder pictured was not a foldable ladder. It would have been nominally 12' long. You're thinking of a foldable ladder which can be transported at half its length.

I dunno. I can't really confirm from the data provided that it wasn't under a 12' ladder. This seems to be pure speculation. Care to provide evidence of your claims?
