Re: LHG 60G experience

Wed Dec 26, 2018 4:21 pm

I've heard that Mikrotik has released the new LHG 60 Ghz R2 review
for range up to 6000m and embedded wifi 5GHZ
I can't find anything on a new R2 version. Do you have any more information? We run 5GHZ backup paths on every LHG60, but an integrated backup would be so much easier.

Please, Ask Mikrotik Directly about the more details
The new LHG 60GHz R2
Have a distance of about 6,000 metar and More...
MIKROTIK is in the testing phase of the new R2 version

there are people on the forum who know more details

The biggest change is in the antenna - the construction
RX and TX
Resistance to rain, snow ...
prices will be twice as expensive

So Mikrotik is making an "R2" (release 2?) version of the LHG-60 dish that will support up to 4,000 meter (2.5 mile)? Complete new design on dish, that allows higher gain and harder to align?

R2 i would buy, building 2 antennas, 2 boards, redundancy + poe switch on tower= no wish at all :) anyway combined should be cheaper than that..

I wonder if its only backup failover, or you can agregate 2 links 60+5ghz at the same time for bigger throughput along for instant failover.

what do you expect more if you bond 5ghz+60ghz? anyway there is 1gbps ethernet port, i dont get your idea (:
my point, just to get ANY connection during bad weather, okay let it be at least 100mbps for snow fall or heavy rain, so the customers would not fuck up to red our phones :)

100 Mb/s is better than nothing :-)

In PtMP scenario with long link 5 Ghz backup (>500m) is an interesting option

What if you go a bit out of range or a little bad weather hits and u dont have 1gb anymore, like have 800mbit, 5ghz would push that 200mbit back giving you full 1gbs again, doesnt matter if u go over 1gbs combined 60+5ghz during ideal conditions which would saturate your gigabit ethernt port, its about quality of service and failover.

Thats one example, besides why not use both links at the same time?Instant fail-over without interruption, isnt that the general idea?

I see everybody suggesting a specific 3rd party precision alignment mount but nobody suggested the Mikrotik solidMount
https://mikrotik.com/product/solidmount

It does look proper for the job and it is actually half price from the 3rd party one. Has anybody got any experience with it? Is it any good?

Re: LHG 60G experience

Thu Jan 03, 2019 12:40 pm

I have 5 different PtP links that I would like to upgrade to 60GHz.

The distances are:

40m
160m
185m
460m
1280m

There is never any snow and heavy rains are rear. I was planning to use LHG60 wireless wire dish for all of them but somebody suggested that the dish would not be good for the 40m link and that I should possibly use the wAP60G for the short links.

What is the problem with using the LHG60 for shorter links? Oversaturation of the receivers? If so, can power be turned down? I would prefer to use the small beamwidth of th dish than the very wide beamwidth of the wAP60G if I can avoid it.

My only requirement for all these links is max throughput and as close to the quoted gigabit speed as possible.

Any suggestions from people with experience on these shorter distances?

Thank you in advance

No problem for the short one use a WAG60+WAG60, for the middle two use WAG60+LHG60 and for the last 2 use LHG60+LHG60

if the 5 links are on the same tower remember that 64800 MHz overlaps partially 66000 MHz so you have to separate LHGs in angle and distance.

Use higher channel for longer links

Thanks server8.

The question is why is it a problem to just use LHG60 for all of them? Do the LHG60s do not work over short distances? And what is their minimum distance?

I could not find this info on their specs.

The links are not on a tower but on a roof of the same building. I can have about 5 metres distance from on to the other if needed and they all look a t a different side except two

Hi, we have 3 different installations,
Fisrt- 1.183 mtrs. above 60 percent of signal where both sites are visible each other.
Second- 806 mtrs same conditions before, no more 80% of signal
Third- 679 mtrs same as before 80% of signal.

The best speed in TCP is 500Mb upload and donload in send/recive mode, with 80%, in 60% we are talking about 150 Mb in both directions at same time.

But we have a problem, at first group, with default configuration, and both 60G connected, do not ping response

What do I have to do for repair this? Please help me.

I think you can use LHG60 without no problem but the wag60 has beamforming antenna with a narrow beam, for the shorter link is easy to install and manage.

For the colocation you have to make some test there are no reports from other users with 5 x 60 ghz radio in the same site.

Please tell Mikrotik that they will do the test on LHG60, will be stable 8000 meters, no way man :P

Tests in Poland [weather,rain, snow]
LHG60 - LHG60 - max 700m-900m stable on 64800MHz at 1/1Gbps [snow, mainly the rime kill the antenna]
Dish 400 Feeder - Dish 400 Feeder - max 1500m stable on 64800MHz at 1/1Gbps
Dish 600 Feeder - Dish 600 Feeder - max 2500m stable on 64800MHz at 1/1Gbps, we tested 1738meters, rssi -60 so at -69 will be 3000m

In each country will be different; different conditions, different humidity, other damping etc.

Why do you use the feeder, now?
Your first setup was: LHG with alu dish AND cover. What's the advantage of the feeder?

Full Solution for electronic LHG60
* better beamforming, because the electronic is perfectly center of the dish without any deform
* is possible to make 5ghz backup
* have waterproof gland on the back of the antenna so you can easly dismount from the mast
* mainly made for PtP Links

Alu Dish 400 without the feeder is only a fast solution to help others cheap dismount the grid and mount the original triangle feeder. This helps to do better rssi and reach more meters in rain and snow, secure from the rime, is full hermetic with ABS Cover... Mainly made for PtMP links, but others use this solution also for PtP links.

Alu Dish will always better than original grid.
Alu dishes will always better also in 2,4 and 5ghz.

Differences between ROS 6.43.7 and beta50 are huge so we have a better solution, the rest will do the software from MT... If original LHG60 will have teoreticaly 1500 meters our solution will have x2 :)

BTest or iperf? On that distances you must have 940/940Mbps TCP/IP... BTest use only one core!!!!!!

No 66000 on that distance!!! Perfect signals etc but you must use 64800 or 58, not 66000.

You cannot use 66, because is only for >3000 meters...

This is standard ALU without the feeder, with the front cover the snow at this point not kill the antenna and the distance is 2x than original lhg.

Can you read at all my posts?????

Frequency: 64800, I write to you that YOU MUST CHANGE 66000 to 64800 on that distance on ALU dishes !!!!

ALU 400 works extremely great on 64800 up to 1500meters

So you are in wrong and you make the basic mistakes my friend :P

RSSI is not and never will be a determinant of the connection quality...

RSSI down to -65 is ideal...

We have at distance 2900meters RSSI -62 so? In this point of view only iperf or btest show us if our link is correct aligned.

.... But RSSI is the only way to determine the signal margin for bad weather. Right?

I cannot install the link while there is heavy rain and snow.

Did anybody else see smaller RSSIs with Alu dishes?

Can you read at all my posts?????

Frequency: 64800, I write to you that YOU MUST CHANGE 66000 to 64800 on that distance on ALU dishes !!!!

ALU 400 works extremely great on 64800 up to 1500meters

So you are in wrong and you make the basic mistakes my friend :P
I do it again today
LHG60 Original VS ALU400mm

the same location
ALU 400 and LHG60

please,
other users to make a REAL test LHG60 Original VS ALU400mm

You have alu dish 400 without the feeder...
No way to get poor signals with alu dish, alu dish is not the plastic grid, alu dish always be better than plastic, aluminium always be better than plastic grid! :P

As I wrote there is also fast upgrade that make stable link in rain and snow, mainly to protect from the Rime, to get better performance and stability, no RSSI... If original LHG60 do 700meters stable, with alu dishes is 1400, 2 x better distance...

Maybe U must off or use 36 beamforming? Do you know about that? :) No tx power at this time.

You can't just make a random aluminum dish and expect it to be better just because of material. There are calibrations done, specifically for the original grid. Antenna design is a precise science, not a form of metallurgy.

@Normis, anything solid is better than this grid, especially in weather conditions as in our north countries. I can't imagine what was You thinking designing this particular antenna. Lower windload but possible total death of link due to snow/water/ice cap? You have Dynadish project You could use to achieve much much better product. but You choose grid antenna. So it's not weird that lot of people trying to fix mistakes of Yours by adding covers, alu dish etc.
AND answer is YES anything of casted/forged aluminium will be better than plastic grid just in matter overall availibility of link/year
Do your product more wisely in next release PLEASE.

LEDs in your picture show that it's still connected

Indeed. Especially remember that the higher the frequency (hence, the shorter the wavelength) the most precision needed.

The only solution I imagine for the ice problems is heating and/or some water repellent treatment. There are specific PTFE based sprays for that. Or maybe something like silicone based lubricant.

I'm waiting for some snow here to try but in 50 years I've seen less than 5 serious snow events.

Best is to use the heat of the radio/board itself. We see problems with snow on the longer links even if it does not hang to the antenna. Seems to have more influence on 60GHz than rain.
