Is it possible to drop a piece of kit which you can then transmit to which in turn sends a signal out so anybody watching/listening would assume your position was where you had dropped said piece of kit?

I can't see why not but then i guess the military would already be doing so to confuse the enemy as to their location.

Thoughts please

Perhaps a transmitter with a recorded message or a series of messages. Any signal you transmit to the dropped transmitter could be picked up and triangulated.

People do something like this to foil other trying to backtrack their IP, using relay boxes near wifi access points.

You could do with transmitters the same way, however, the majority of military comm equipment already tries to mask its presence and you don't see a lot of people in the field that can rdf a spread-spectrum radiator.

That's is what i was thinking but can anybody say categorically whether this would work and give a reading that anybody checking would think you were in place 'a' instead of place 'b' ?

The only way you could do this would be to send the signal over a wire to the remote located xmitter. So if you were attempting to do this over a long distance it would be impractical.

It depends on what you mean by "anybody checking" and the specifics of what technology they are using to check. Deception technology must be finely tuned to the detection technology.

In particular, advanced aircraft electronic warfare systems are able to do this in response to less advanced radar detection & tracking systems. In some frequency bands and in some conditions.

Animal camouflage works against other animals with certain visual capabilities. Does it work then? Yes.

Does a zebra's stripes work against a person in a helicopter at night with good infrared imaging? No.

It could be done by sending a coded message to a remote receiver which would re-transmit an uncoded message over a different frequency.
This second transmission would be the one which would act as your "decoy" and draw the attention of those you are trying to evade.

1. Remote control via wire of a transmitter. Distance is Limited by length of wire.
2. You can set up a transmitter repeater, which you can for instance transmit to on
SHF/UHF or VHF(Short/medium distance) and it relays on HF(long distance). Or relay
can simply increase the distances covered by UHF/VHF. Each part of the link
gives off RF radiation and is detectable though. You can send data in a tight
directed beam to mitigate this.

The UHF or VHF relay system could be spread spectrum which makes its signal
harder to detect.

As others have said, it sounds like you're trying to set up a relay. A neat way to do it would be by microwave. But you're limited to line of sight and set locations. You could use a system like a news van, with a transmission tower. But you would still need someone at the relay location to aim their antenna as well.

You're better off having a set time between yourself and the receiver to listen in. From there, you send a prerecorded and coded message. Send it in chunks and out of order. Within each message will be a code stating which frequency and when the rest of the message will be sent. While not foolproof, it would make intercepting and decoding slightly more tricky.

A more practical way would be to get your ham radio license and join/create a net. Of course, then you can have infiltration and whatnot. But probably more cost effective. (It's also illegal per FCC Rules Sec. 97.113 so there's that too.)

Yes, you could connect your broadcasting device to a control station via a coaxial cable.

This is the same technique used for running cables in the ocean so that they cannot be "listened" in on without physically tampering with the cables. A coaxial cable will negate the electric field outside of the cable. This is confirmed with Gauss's Law, Ampere's law . . . whatever you like. If there is no EM spectrum to be detected anyone looking for the source of the signal would have to manually trace your cable back to the source.

You could run a relay where a receiver is connected via cable and broadcast to the the receiver with a directed antenna such as a Yaggi stick.

If you want the actual broadcasting source to be concealed you are pretty much S.O.L.
