Corroded LNB arm?

[Jockalba]

I have a Lenson Heath 800mm dish, which, though old, is in fine condition (it's aluminium, I assume?), but the LNB arm is becoming quite corroded - can I get replacement arm, or will I have to buy a complete new dish/arm?

a new dish is cheap these days or clean up the old one unless it's falling apart

the price of dishes has really come down in the last few years, i bought a 65cm the other day for an unbelievable £8. 50, +del last week,

lenson dish are not made now but im sure you could make a new arm is need be , i had the 1 metre and found that rain collects in thebottom of the arm so i drilled a hole gave it a good paint and its been fine . no more rust

I did have an arm some where but it's cheaper to buy new all alloy if possible
