Bob, it's really not all that difficult to replace the contact on those relays.
Most of us have had to do that in the past. First locate some GOOD contact
material. Even a old relay, preferably surplus, will have contacts similar to
those on the relay post you have. Even an old washing machine "brain box" will
have lots of relay contacts. All of these are probably Silver-bronze material.
Then you will have to find a way of silver solder those contacts on the
old stub of the defunct antenna relay. Soft solder probably will not work but
it has for years for me at the 100 watt level. KW, not so. Keep the old
dimensions as you do not want to have a short with the relay unenergized! After
all, this is all that the original relay manufacturer did to produce a product!
You can do as well and somewhat better than that in the long run. Cliff K7RR
