    Would a broadband jammer prevent enemies from being able to set off their IED's when US forces pass by them? Maybe there could be timed breaks in the jamming that allow communication to happen (but only if the listener knows exactly where and when those breaks are).

    I'm just thinking if I were a soldier in an area with a lot of IED's, I'd probably want a jammer running whenever I drove places.

    A jammer would work, but interfere with their communications also... at least in simple form.

    Modern military communications uses "frequency hopping" and is even part of the encryption. A jammer could be built to jam the spectra not used by communications, and instead of hopping to a frequency, it can in theory, be linked with the commo gear and leave a hole in that part of the spectra for communications.

    Great idea if you have a way of marketing it to the DoD.

    The signal wouldn't have to be strong for vehicle mounted jammers. Just strong enough to overcome a distant trigger signal.

    Such devices are in common usage. They do not interfere with friendly communications.

    Have they been very successful at stopping IED detonations?

    I am somewhat confused as the central premise of the OP. IEDs are, by definition, improvised, and besides that... most are based on pressure... not remote activation. Am I missing something? How would jamming broadband signals have any impact whatsoever on a pressure sensitive device (i.e. one that explodes after someone steps on it)?

    I assume you are referring only to a small subset of IEDs? Just those which are triggered remotely, and not those which are pressure sensitive or set on timers?

    Yeah. I was thinking of cell phone bombs, and other ones like that which are activated in person by a terrorist.

    A pressure sensitive IED is basically a landmine isn't it? What would ensure that the bomb doesn't kill ordinary citizens, instead of American GI's? If you leave a landmine on a main through fare, there's going to be a lot of people other than Americans stepping on it.

    A pressure sensitive device placed on a road would be triggered by a civilian vehicle, rather than the intended target. IED's triggered by cell phone are some of the most common. If not by cell phone, they are alternatively triggered by affixing a car battery to a wire but this leaves the ignition crew at higher risk. Cell phone interfering devices have been effective, but there are ways around it. I would not like to elaborate on their operation or success rate.
