Having a wooden pole appr. 12-13m high. Putting up 3 wire verticals, 80m (Inv-L), 40m (Inv-L) and 20m. They are separated some 0,5m out from and spread around the pole, each having 2 elevated tuned radials. Each with it's own coax feeder. It would be very easy to put short jumper cables betwen the radials and connect them together.

If radials on ground I think the answer would be obvius, just put as much as possibel copper in the ground ;) But what about elevated radials? Any benefit with connecting the elevated radialsystems together, or not?

Any comments appreciated ;) been Googling and reading the antenna handbook but don't get any wiser .. hi

If they are tuned and you connect them all together they will then become un tuned so you will lose any "benefit" . you will probably change any radiation pattern you have now and may in fact end up with all manner of issues ..

Well that's what I been thinking to. But, on 15m f.ex, will the radials for 40m resonate as if you compare with a 40m dipole that tunes well on 15m? in case they do, will they add to the groundplane? I wasn't sure on how to think about it ;) Of course playing safe would be to not to connect them together, but would like to know for sure. Would be interesting to get a theoretical explanation as well ;)
