They exist, but there doesn't seem to be a great reason to grab one yet. Companies have added the 6ghz band but not more capacity...so before you may have had 2 5ghz antennas...one for backhaul and one for clients...now you have to choose whether you want backhaul or clients on a particular frequency, and both are suboptimal. I'd recommend just buying a nice wifi 6 system that puts clients and backhaul both on 5ghz. I routinely pull 500mbps from a satellite on a wifi 6 mesh network(asus xt8), I don't see much need to upgrade.
