Mikrotik 6Km PTP radio link in a eolic tower

RouterOS Wireless Networking

Hi all,

I’m trying to “design” and then implement the following scenario. A PTP 6Km radio link between an eolic tower and another Tower.
The first eolic is 6 Km over sea (so i need IP66 enclousre), the second tower is in coast.
Maximum throughput 10mbps.

My question is, what kind of antennas do i must use to establish the link?
I saw qrt 5ac, and DynaDish 5, but they are not IP66??

Thanks for your help and suggestions

I’m pretty sure it will handle.
I don’t think any antenna system has IP Code in datasheet.

Hi,

I have a PTP link using QRT 5ac for same distance, 6km over a plain field. Both QRT are mounted on 20m height on water tower and 25m on a granary ( grain elevator) since december 2015.
It has been pass throught 2 winters and enought heavy rains and are still online. In fact, link never went down since installation ( obviously both are grounded and are connected to UPS too ). From this point of view i am pretty sure that are quite resistant to weather conditions from your scenario.

kind regards,

Thanks for your help and indications.
They are very valuable to me.

Putting the device on the sea is something different than just on plain land. I would rather enclose the device into another enough resistant plastic box.

It might be hard to find boxes that fit DynaDish or qrt. Even so, you must to build a strong mount for a thin plastic. Water sealent might help.

I’d either dissasemble and tropicalize the QRT, or go straight to a enclosure + RB (and tropicalize it too), e.g. RF-Elements Twistport adapter or the like.

QRT is going to stand weather (to a degree, sea/ocean climate is really corrosive), given its cost, it may be easier to just preventively replace units on a year or bi-year fashion than to try to make them corrosion-proof.

The key here is choosing the most integrated and self-contained product, the less mechanical connections, i.e. the less connectors, the better.

Pay special attention to the RJ45 receptacle, as that’s the typical point of failure corrosion-wise. Either use some putty after plugging the cable, hot glue, or anything to prevent air to reach the RJ45 connector pins.
