Is it a power antenna? If so, see below:

Replacement masts run under $40 here in the US.

I am working on putting a short flexible antenna on my '85 to replace the power antenna. It is a little tricky as the stock mounting hole won't accommodate the aftermarket units I have tried to install due to the mounting angle and the inner fender wall behind the hole. Should have pictures and a writeup on the swap once it is done.
