Why would you go to all that trouble when they have a fuse already ?
Besides, how does this ‘radio control’ plan work when the receiver is locked inside a THICK STEEL PAN ?
Solder your antenna wire to the lid. Easy.
a 2.4ghz RX with a 1/2 mile range has a 1” long antenna. the RX can be on the ouside of the bomb and the wires go through a .032” hole drilled in the case to the detonator.
These guys were a couple blocks max from the bombs... easily within the range of the cheapest 1/10 scale RX car electronics.
Its a good thing most terrorists aren’t too sharp, because it doesn’t take a rocket scientist or a lot of money to build an RC bomb.
A 20 model 2.4Ghz RC TX can be bought for $60, meaning someone could theoretically bind 20 different $6 RX’s to 1 TX and blow up each separately. I’m confident there is a Prepper out there right now with 20 RC Claymores on his property.
