Here is my test result
I had replace a lot of ubnt radios with LHG and gain was between 10-30dbi better than ubnt in the same spot. It’s a winner for me. Not to say most of them didn’t even had LOS. Now all signals are under -60 and previos where -70 to -84. Not to mention the price and the fact LHG doesn’t rust.
Your 13dbi mismatch between chains means bad alingment.
thats not a ptp link
thats ptmp link
Is the comparison in the first message a link between a LHG and M5 400, or is it a comparison
after replacing M5 400 with LHG on the same link? And was that replacement at both ends?
i didn’t re please them
they both are active
And what is at the other end? The same 2?
both of them are connected to the same AP (RB911G-5HPnD)
The mismatch depends on the antenna specs of each equipment.
They use 2 chains and usually they manufacturer use 2 different polarities in the same antenna arrange, The antenna on V Pol and H Pol doesn’t have the same radiation patterns and the same gain at the same frequency, that said, If you have an 24dBi gain antenna on the CPE and on the AP you have a 16dBi Sector antenna for example you will have a 8dBi Difference between the Access point and the CPE and there is your mismatch, also its proportional to the TX Power on each radio.
Now, the signal isn’t everything, you’ll have to check the CCQ and Tx/Rx rates and see if they improve. In No LOS scenarios sometimes you have a nice signal (multpath signal) but a crappy data rate so a greater signal isn’t always a better data throughput.

As I can see the picture u posted… the difference could be the slit height and alignment issue. The UBNT is higher that the LNG just interchange the position and do a proper alignment and see what happens. Secondly please ensure that u are using original OUTDOOR CAT5 cable else u are bout to have losses.
the problems are radios not cable
What is the antenna gain on the AP?
RB911G-5HPnD
Now you are suddenly talking “problems”…
Do you have a problem, and what is it?
I’d upgrade the LHG to latest stable version (6.36.2) for starters.
Have you done the tests switching off the other radio? (ubnt shut off while testing LHG).
Wouldn’t be surprised at all it the LHG is being hit by the PBE at a signal higher than -40dB, “deafening” it.
Do actual TCP traffic tests, ubnt Main info can be misleading to say something soft.
Use nstreme or nv2 once all the basebox clients are routeros devices. 802.1 isn’t going to scale, specially in PTMP.
problem :
my PPPoE account limited at 40mbps for dl
when i use it on RB LHG5 its OK - download speed is 40mbps
but when i use it on Powerbeam the download is 7mbps
Like the powerbeam would be the source of the problem…
and when i use vpn client on PPPoE ( On powerbeam )
there is no problem with dl speed ( 40 Mbps)
just change frequency on ap side down to 5400-5600 range and look again
