ive never looked, but do they do higher focused directional DVB arials than a yagi (but not as focused as a dish) ?
the thinking being if you can use a cheap commercial higher focused arial and also increase its db gain at the same time, that will go a long way to remove the Co-channel interference providing that second EU transmitters not within the same degree angle as the new focused receaver....
hmm, putting my DIY/cheap hat on, perhaps you could make a generic mesh cantana enclosure of the right dimensions to make a generic yagi become far better at excluding this Co-channel EU interference and narrowing the transmitter beam angle pickup at the same time ?
wire mesh to allow the wind to flow through it if its outside OC, and you need to work out the right diameter and optimal focal point to place the dipole part inside.
for fun, you could go the easy route and hack the dipole part of a DVB yagi onto the focal point end of an old parabolic sat dish OC but your going to get freesat if you are going to do that anyway
but then the man in a van with a ladder, will be most peoples first choice
