TV aerial corrosion

I have a problem with corrosion on my TV aerial.It's made mostly from aluminium but is held together with 3/16 inchgalvanised steel screws, as are all the aerials that I see anywhere.There are 11 round elements, 6 of which are electrically connectedalternately together by flat pieces of aluminium giving a total of 24pieces of aluminium that touch each other, clamped together by thescrews.About every six months TV reception gets bad, and I fix this by takingthe aerial apart, sanding the surfaces and putting petroleum jelly onthem. I used to use CRC but that lasted only a month.It's really difficult to do this because the aerial is 10 metres up ona roof with a 60 degree slope. TV reception is really bad here so Ineed a large outdoor aerial as high as possible.I have tried to get aluminium screws but without success. They wouldprobably be too weak anyway.I imagine that stainless steel screws would still cause a problem.I have considered taking it somewhere to weld the connections togetherbut it's about 2 metres square and fragile and rather hard totransport.Any brilliant ideas?
