Good day!

I’m planning on using an ELS61-AUS in a new project and I have a question about fallback options. The 4G frequency I need to run at is 1800MHz however the 3G fallback will be 900MHz. I’m rather limited in the antenna I can use (basically a whip) so I’m wondering if I can use the diversity antenna port for a fallback 900MHz antenna and the primary for 1800?  I’m not sending / receiving any data so I don’t need the diversity antenna for diversity. My alternative I guess is an external RF switch.
