Is it okay to operate the Electron w/o cellular antenna?

During initial development, I’m running my Electron in SYSTEM_MODE(MANUAL) mode and not using cellular connectivity (yet).

It’s a small matter, but I’m wondering: will the RF power amp or RF circuitry be bothered if I don’t connect the cellular antenna? It would make my life epsilon easier…

Doesn’t sound like there will be any issues with that.
