I have line of sight from the top of a mountain in Kamo, over Whangarei, to an address near Onerahi Airport where I'm looking to beam a UFB connection from.

Based on Ubiquiti AirLink stats does this looks feasible with 2x Ubiquiti LiteBeam 5AC LR or do I need to make more allowance for noise floor of Whangarei / Onerahi Airport (anyone happen to have any measurements?), cloud / rain etc?

I wouldn't contemplate using a Litebeam - I'd opt for something a bit bigger rather than the cheapest radio they make.

Is there any reason why you're looking at 30MHz channels?

You have a clear line of site. Pretty much can do whatever you want depending on budget, unknown variables (like noise) and how fast do you want to link to (possibly) be.

Over the 9km link I have ---- I initially had Powerbeam 5ac gen2 setup...and then upgraded to airfiber 5XHD with 30dbi dish.

I'm guessing you're up Parakiore? Given that most of Whangarei can see the top of the hill, and is a damn site nearer than Onerahi, I would have thought finding someone closer to help out would be your best bet.

I'm in Kamo, but sadly don't have a line of sight...

Yea grab some bigger PowerBeam's. Or if the budget is there, some AirFiber kit.

Obviously looking for the cheapest option that will do the job for consumer application i.e. where 90%+ reliability will be good enough.

30Mhz is what AirLink tells me I need for my target 200Mbps, although still shows "100%" connection up to 50Mhz / 382Mbps so I figure there is some margin in there.

What ecconomical hardware do you suggest?

I'm open if there is someone closer who wants to help out until then Onerahi is our best option - and the angle may actually help avoiding trees on our end.

PowerBeam 5AC Gen 2 only shows 90% link at 30Mhz / 199Mbps so doesn't appear as good as the LiteBeam Long range?

Yes I think AirFiber is above the budget unfortunately (looking ideally <$600) and isn't the higher frequency more suseptible to rain fade etc?

There are a handful of PowerBeam options. Probably just want to grab the high gain option and then pull the power back to a nice level.

Tried all the other PowerBeam options but none of them seems any better (all drop off % at a lower bandwidth) so not sure what to make of that?

By the way this is the current line of sight hence cloud penetration will be a factor...

Would Ubiquity PowerBridge M5 do the trick? Slightly older technology that maxes out at 150Mbps, but I've got a pair here sitting doing nothing.

I'm willing to send them to you to play with and try out, if they work for you pay me however much you think its worth to you.
