How do I add my new Arlo Pro system to Redport Halo system

[Devocean1121]

I have installed a Redport Halo wireless repeater/wifi booster in my boat and would like to use the arlo pro system.  The wireless wifi extender does not have an extra Ethernet port to use to plug in the arlo pro. The only Ethernet plug has to be used for the antenna. What are my options? Can I use a USB type wifi antenna plugged into the arlo pro to connect to the wireless wifi repeater? But  It does has a "SAT" plug port on the extender too. Can this be used somehow ? Thank you

The easiest thing to do would be to use a switch to expand the number of Ethernet ports.  Another choice would be to use yet another WiFi extender to gain a port for the base.
