[time-nuts] Help needed IDing GPS antenna

[John Miller]

Hey all,
I'm looking for a specs sheet for an antenna i recently got my hands on. It's marked Topcon on the top, II Morrow Inc model 590-1114 on the bottom. I've tried searching in all the usual places but haven't found anything yet. If anyone could send anything my way that would be much appreciated!
