Herelink Technical Specs for validation/certification

Need some help please, on the herelink module (ground unit) specs to properly ensure certification. Can be this one or the newer 1.1 (1.0 is HX4-060107):
1- RF Power out of the Module in mW. I trust it is 2.4 Ghz Wi-Fi.
2- Dual antennae, Diversity? Or is one receive and one Transmit?
3- Technical rep contact info, to BrentO@OlsenTechLLC.com.
Thank you.
