hi every one ..im planning to connect ( metal 5shpn ) with ubnt sector 120 degree using LMR cable …any body have an idea? .can i do that? is my idea good or not ??

Remember the Metal 5SHPn cannot be mounted horizontally but has to be vertical and what type of connector is on the UBNT antenna.
Why are you connecting a single connector device to a MIMO antenna?
my dare..the( Metal 5SHPn ) is just an access point ( i will use it ) and it does not understand things such as H /V polarity …the H/V polarity are in the sector antenna but not in the access point …
i have a sector .and i connect it with rb433+sr5 (350mw) with just V polarity .and it works fine without any proplem
Mikrotik recommends not to mount (screw on) and position horizontally the Metal 5SHPn, see from product info;

Dimensions 177x44x44mm, 193g. Must be mounted with ethernet pointing down
i think you misunderstand me…the device is not produced for just ominiantenna..you can connect it with sector antenna using ether v or h port in the sector ( by using LMR standard cable )..that what i asked about .
So the 433 + SR5 is already driving the vertical on the sector, you are asking about the Metal on the horizontal polarity?
It will work, but you will probably have a bit of self interference. It would be a wild guess to say how bad.
you also misuanderstand me …all what i will do is /
1- fix the metal 5shpn beside the sector antenna .
2- connect the metal with sector by using LMR standard cable
3- connect this cable into v port ( just v port ) in the sector ..so the sector will work vertically ( just vertically ) …
Ok yes I misunderstood as in your pictures was just the two items and I assumed you would just screw on 5SHPn direct to the antenna as most would do and had not considered using LMR cable but maybe using a 90° N connector adapter but ensuring that this adapter does not rotate in windy conditions is difficult unless you can customise a bracket from the antenna to the 5SHPn to prevent this, as regards LMR cable can I ask will you post back signal results with LMR and then with 5SHPn attached directly to the antenna, I would like to know the actual onsite insertion loss rather than the quoted loss published.
I still don’t understand why you are connecting a SISO device to a MIMO antenna.
Yes, it will work.
