Antenna setup recommendations for increasing bandwidth

Wed Feb 12, 2014 6:19 pm

Most of our customers are located between 6-12km away from us. Our furthest away customers cannot sustain more than 1-2MBPS of TCP throughput.
How can we improve our situation without changing location? We need advice on improving CAP setup and CPE setups.

More details below:

Our CAP setup is a RB411GL + R52Hn + AirMax-5G19-120. We currently have around a dozen active customers.

Our customers are situated up to 12km away, with signal strength as low as -80 to -85 db for the customers furthest away. For customers situated under 3km away we use SXT-LITE5, for those further away we use SXT-5HPnD. (16dbi gain, 1.25W TX strength)

We are active since about three months and we haven't had complaints regarding reliability, not even from customers > 10km, but bear in mind that most of our customers are on our cheap 2MBPS package.

Ideally we would like to add another tower closer to our customers but it's proving quite difficult to find a location at the moment.

So we have to find alternative solutions to improve our throughput to customers.


For example we have a customer which wants 3MBPS internet, and who is currently sitting between 1 and 2 MBPS. He is 9km away and is currently connected via an SXT-5HPnD.


What can we do to improve our current situation?

Invest in a different CAP setup? Buy more powerful CPEs ?

Need harware recommendations. I know I haven't provided too much info if you need any more details please ask.

Thanks in advance

More powerful access points will not help.
You'd better invest in good directional antennas.
Example a groove with a good directional antenna

Should I replace my access point [and 120 degree sector antenna] with say, six access points with directional 20 degree antennas? Of similar gain?

Is this what you are saying?

you can try this

The less the beam angle the further the link will rich and more stable

You need a higher gain antenna on the client side for the far out clients. 25dBi dishes with RB911s would work. There isn't really an elegant solution from Mikrotik for your situation.

Running the sector you have with a ubiquity Rocket and nanoBridges would be a better solution for future deployments.

The SXTs have longevity issues which you will discover soon enough.

Nanobridge from ubiquiti is good for point to point links indeed

Mikrotik why you such a thing manufacture as the nano bridge?
This would be very good and appreciated

I'm looking forward to it :D
