SXT questions

Tue Feb 05, 2013 4:53 am

Hi all.

I just purchased a few new SXT g-5hnd units for testing. I thought all of the new SXT products were going to have a ground screw instead of the loop? Is this old stock or am I missing something?

Also, I am looking at a project that has 3 out buildings that I need to install 3 IP cameras in each. Distance is really short at .04km would you use SXT's or build up a radio into something like an IT Elite enclosure. I have some concerns on water / ice issues with the SXT's still.

Also, anyone have any opinions on using the Omnitik as the AP or would you go ptp to maximize thruput?

I was thinking of ptp links with a 2011 on the roof and then run fiber down to the video recorder

I did some testing today and was able to push two SXT's into an omnitik at about 30mb per sxt. omni had about 70mb of data on it. I had a 750g at each point to use as the bandwidth test tool. I assume I could get about 15 to 20mb with 3 SXT's on the omnitik.

I have tested about 100 SXT's in cold Norwegian winters, and quite rainy climate, about 1,5 years, and I have still not any SXT that have broke in field.

And we have tested around 100 in the UK and have had around 10% fail rate due to water ingress - only the ones we silicone extensively survived. In my view, (we have around 2,000 Mikrotik radios in the field) use a different solution: Maybe the OmniTIK as distances are not that great, or a 5ghz external radiu from Engenius or UBNT as they are so much better made.

We have around 800 SXT installed, no problem with rain.

SXT works well, but has 16 dBi antenna only. For mentioned 0,4km it's definately ok. For longer distances I propose to consider ... -20hv.html + RB711G-5HnD.

What about a 750UP powering three SXTs instead of the omni? The SXT to SXT links at that distance should be right around 54 mb. Three of them will not saturate a fast ethernet link from the roof to the equipment in your building.

I will be deploying SXT onto a dish antenna but have plans to seal (allowing a small vent hole) and have short Ethernet fly-lead from the SXT to a IP65 box and connect to down lead there, water ingress is a major consideration.
