Unifi Comparable to Ruckus P300

Good morning

We use Ruckus P300 in most wireless bridge deployments and it is ROCK solid but they are 2k a pair which is a bit steep for one of our clients, especially considering we need two sets currently.

I am looking for a comparable Unifi setup with 1gbps throughput ideally, but depending on price we might consider 450+ mbps.

Distance is a couple hundred feet, clear line of sight, no obstructions whatsoever.

I need two pairs or one pair that does point to multipoint. Also I am really not sure we need external antennas for a 300 foot throw, but they all seem to require antennas of some sort.

There are so many models, AirFiber, Airmax etc.

Does anyone have any recommendations?

Thanks
