Cross-posted to sci.electronics.repair / misc, as I didn't know which
one would be most appropriate.

Anyone know of a RF noise generator / jammer, that could operate in VHF
frequencies? Preferably in UK / Europe. Ideally a radius of 20-30 metres
. Even a circuit for a home-build may do, although I am lazy

Any spark/pulse type circuit is rich in harmonics, well through the VHF
band.

One can optimize the output energy for a given frequency range. But, what
you propose can be deleterious to neighbors and is generally not legal.
