Client has 49dbi receive, tower gets 71dbi from client.
Tower: 150ft
Wrap-SR2-17dbHPol Pac wireless
1.5 miles Perfect LOS.
Client
RB532-R52-19dbi arc wireless 30ft.
I have adjusted the aim and signal only gets worse.
sr2 and sr5 have bad sensitiveness, try to put normal atheros 5213 card , I tried TP-LINK WN-551G PCI and got -58 , for example with prism 2,5 3com oem / tonze I got -70/-75 300m to client, apc with panel antenna.
miahac -
There are lots of varibles not mentioned in your post - I’ll try and name a few for you to look at and we’ll see what happens… I am sorry if some of these seem obvious but without seeing your setup some clarification is needed…
First - have/did you put the R52 card TX power in default mode? MT OS ‘knows’ this card and the power out. Setting it manually can sometimes cause unwanted results.
You mentioned that your AP antenna is a HPOL - did you also mount the CPE antenna in the HPOL configuration?
You also realize that the power out from the R52 is 11dbi less that the SR2, and your antenna only makes up 2dbi more so looking at your real world figures the best you can get would be around -60dbi…
Do you have other clients on that AP? If yes, what do their signal strengths’ look like?
I didn’t look up you AP antenna but I am guessing that it is a sector antenna, how does your client fit in to the sector - dead on, off to one side, or what? Also have you pointed the AP antenna downward at all? If so - how much? How does that angle fit with the CPE position?
I know - lots of questions miahac but need some answers to to give you a direction to go in…
Ok miahac, I’ll be watching the topic - get back to us when you have something.

does the tower have other clients connect? how are they?
i’m assuming you mean RSSI, not dbi..
we saw this same issue, but the problem was we were too close to a 480volt electrial line run around a trailer park…every channel exhibited this, until we move 90 degree antenna further away from line…then all was normal
EDIT: You tried chanhing channels? what is the wireless->status-> noise floor reading?
Yes I tried manual, default, and regulatory domain.
Yes, and double checked
Yes. I was expecting about -60, The difference though is not 11db, only 9 and the output power of the sr2 drops at higher speed, so should only be 6.
This is where I should be looking, I have a 15dbi rootenna with a 200mw generic b client (engenius) across the street with only -60 but the power is backed off all the way. I do not know the clients signal because it is reported in %
Also a good point maybe I am getting a reflected signal from the tower or some kind of multipath.
Thanks, Jeremiah
I have loads of noise, -91dbi. If I do a scan from the tower for 802.11 ap’s I pick up about 50 in each direction.
I meant -49 and -70, so the tower has the weak recieve. I will probalbly be switching the 17db sectors to 12db, and one sector at a time to nstream with 5mhz channels to clear some of that up.
well i did not solve the signal gap but i did fix th the dropping connection.
Signal was too strong. I put in manual tx power on all my ap radios to a max 23db, and all the drops went away. noise is still high though.
