Storing Antique Radios in Winter

[zombie1210]

My summer of acquisition is over. I now have way more radios than I can realistically keep in my home. Some are restored and some are not.I have an unheated storage unit.

Any tips on what I should do to protect the radios in my storage unit from any damage that may occur over the winter? We get below freezing quite a bit, but not usually down to zero.

Insulated blankets?

Don 't worry about it, they will be fine?

Just don't turn them on until they've been back in a a warm environment?

Thanks
