SXT that we would like

Hardware MikroTik hardware general
1

The RB-SXT would be an excellent product to be used in multipoint because
1 - There’s nothing to assemble (it is ready to use)
2 - It has built-in LED signal for easy alignment
3 - It have MiMO 2x2 and this maximizes spectral efficiency
4 - Very practical

The problem is the LOW GAIN!! :frowning:

Now, I ask because it will not released a more suitable product to the real world, ie
1 - A version with integrated 20dB (I think is the minimum to connect customers with the maximum modulation up to 7-8km)
2 - A version of the same except with 2 external connectors for a high-gain antenna (for customers of up to 20km)

The actual version has a gain of 16dB too low to be used in large scale on PTMP

Is there any prevision to release a SXT-20dB and SXT-ExtConnectorized?
:slight_smile:

It would be the perfect product that reflects the needs of us (Wisp)

I would start to improve our distribution network by installing and connecting customers to BTS 2x2 MIMO up to 20Km with decent signals (-75dB)

How many of you are interested?
And Normis, what do you think?

I think the product is fine.

I think the solution to your specific issue is already being addressed by many other individuals.

SXT Reflectors!

much more elegant solution. and very cost effective.

external connectors would mean “there is something to assemble”. why can’t you use RB711 in a box and any antenna you choose?

4

We have already tryed to use offset but the result was not acceptable

Because with the RB711 and the box there’s still much more to assemble and the rb711 isn’t MiMo 2x2

Offset reflectors are working very good. 10dbi more with 55cm.

please resize and rotate images before posting. it was 3Mb total, which is too much for some regions

Sorry, here everyone has 100mbps :smiley:

I tried a
RB711 + Grid 90cm x 60cm
vs
SXT + Offset 60cm

On the same AP cell with the Offset+SXT I got 3dB less than the other.
I thought that would make something better of the grid.

Probably would be better with a 5Ghz real feeder? SXT is too large to capture the perfect focus?
Have you tried the same offset dish with a real 5Ghz feeder?

The problem remains, however, on the sxt 16dB (up to 7-8km… call it standard antenna).
As I understand, many people say it would take at least one 20dB

9

it would take at least one 20dB

with more than 20dBi it would no longer be a low cost product for everyone

10

Yes. But we need cost efficient not low cost. If I’m in need of a 20db CPE I’ve to
pay the price. It does not help there is a low cost 16db if I need 20db.

11

we are trying hard to please everyone, but it takes some time :slight_smile: we only recently started with the integrated solutions

12

Of course but If we wouldnt beg you it might take longer :smiley:

13

use RB411 and http://en.jirous.com/antenna-5ghz/JC-320 - 20dBi?

14

Low gain? Say what? My friend built new base station recently with Dual-Pol 17 dBi Sectoral antenna (HV). Radio was standard power (100 mW) and he did a quick test with SXT 5 km away from base station. The signals were STABLE -68/-69. SNR was great, CCQ near 100% and the best part - throughput. SXT could upload 20 Mbps and download 70-80 Mbps. Traffic was generated from laptop using Bandwith test. All stable. Period.

What was it? Low gain you say? Nah :slight_smile:

15

if you want to be rude, do it on some other forum. if your results are bad, blame your setup, not the person who did it better.

16

What was it?

hey Normis, calculate it in wifi calculator. He’s lying. Such signals are not real 5 km.

Life is not just positive.

change your calculator

18

just tried http://www.radiolabs.com/stations/wifi_calc.html, sounds plausible to me…
May be your calc is lying.

19

ok, and now… SXT has a 26 db tx power only when the data rate 6Mbit/s, yes? When MCS15 has only 19 db, yes? Now, put both sides into the calculator. about -72dB in the ideal state. The added noise, a reserve… SXT has a small gain. Intercede for the offset reflector as the canopy.

calculators already include some loss, and they add cable loss which is not there for the SXT. stop looking at the calculators and buy one SXT for testing. this is nothing spectacular, normal SXT performance
