Does anyone have insight on exact configuration of a 900 connectorized sm with a 13dbi yagi. Having a horrible time getting anything from outside of the footprint that we can service with the non-connectorized sm.
Our tower just has one active connectorized Ap with a 360 cyclone antenae.
the Ap is set to 40 miles, we have tested many different residences in every direction at 4, 6, 10 miles and can’t get anything. I have set the sm to 36-13=23dbm which is the proper configuration. It just doesn’t make sence that we can’t get anything, the yagi works great where we have clients online with non-connectorized.
Could closer sm’s that are still at default dbm be cause desensitization of the AP so the futher sm’s won’t get connectivity. Any thoughts would be much appreciated.
You indicate that the integrated 900’s work fine, but connectorized with yagi’s do not work? The gain of an integrated is 12.5dB, only .5dB higher than the integrated. The actual power to the antenna is about the same through the connector. What you gain with 13dB Yagi is slightly narrower dispersion.
With that said, the ONLY thing I can think of is polarization. The yagis ship for vertical polarization. You have to remove the bracket and rotate the antenna so that the elements are horizontal (i assume the omni is horizontal since the integrated work fine.)
Make sure you are not touching the antenna forward of the back elements when doing a survey.
While the problem you describe is likely polarization, you mention power levels. You want to set the SM’s so that their power at the AP is -75 to -65. If you have an unusually high background RF level, then raise your window so that the lower limit is 10dB above the noise floor. If you have 4-5 SM’s with -45dB at the AP you are in fact desensitizing the AP.
I talked to a local competitor and they dont install the customer enless the power lever is -75dbm or stronger! Shoot, 79 looks good to us… no wonder they drop all the time. :oops:
So if I turn down the radios that are closest, and there are a half dozen at 24dbm all about a mile from the tower to about 10 to 13 dbm it should make things a little quieter, so the sm’s 6 to 10 miles will have a better chance to see the ap and register on the network.
The yagis are a mystery, i am wondering if the 13dbi are too strong for the area 6 miles away because when my techs couldn’t see anything with the 13dbi the 10dbi saw the network but the signal still wasn’t as good as the original non-connectorized that was in place. This is definately a frustrating experience for us.
Wireless. -79 would be OK if the noise floor was below -90 which is not likely. You can deal with this by using a higher gain antenna on the SM.
Sinned, yes turn down the closer SM’s. Start lowering the SM’s power level 2-3dB at a time until the AP sees the SM between -75 and -65. Don’t drop too low too fast. If the level drops too low, the SM won’t register and you will be rolling a truck. 
This will improve the performance of your remote SM’s. We have SM’s as close as 2 miles and as far as 15miles on the same AP.
A 13dBi would not be too strong at 6 miles, that would fall in around -60dB which is a little strong, but not a problem.
Are you sure you have 900MHz yagis? This is sounding like you might have 2.4GHz yagis. Otherwise I think you got a batch of bad antennas.
Thanks Jerry, i am personally going onsite tomorrow to test the gear. You may be right and the antennas may be a bad batch, I hope not though. This is delaying our deployment to many excited customers. Thanks for the advice on the closer sm’s too. Much appreciated.
Can anyone tell me if there would be a difference in connectivity and signal reception between a 13bdi yagi from pacific wireless at 100 watts and a cushcraft 200watt 13dbi yagi. We were supposed to get the cushcraft but our supplier decided to get the pacific wireless yagi instead because of delivery time and cost. But they are not working for us at all. Very poor signal, if any, at various location in our 4- 10 mile test footprint. Should we go with the cushcraft? I told my supplier to go with the best quality and not to worry about price point. We are not very impressed with these at all. We followed the dbm setup for the yagi’s 36-13=23dbm in the sm. Tried different sm’s and yagi’s and for the most had nothing. Where i have customers 8 KM away connected with a non-connectorized sm, I had very poor signal with the 10 and 13 dbi yagi on the exact same roof as the non-connectorized. Has anyone used these in rural areas with nlos/los and had the same issues?
As long as you are orienting the yagi properly (horizontal) and are not touching the element while testing then it whould work fine.
We use the Cushcraft with very good perfromance. I think you got a bad batch. Obviously this can be confirmed by getting a cushcraft and testing with that.
I am picking up the cushcraft yagi’s today…thanks. Just curious Jerry, what kind of distance in miles do you get with the 10 or 13dbi cushcraft yagi in a rural nlos enviroment? 6-8-10 miles? under a medium path interference?
We are in one of the worst RF environments - San Francisco Bay Area - Contra Costa County. Noise floor is about -82dB to -85dB.
Radios are on a 3800 foot mountain with lots and lots of dishes, transmitters, etc. Nearest customer is about 2.2 miles (SM power is turned WAY down). Furthest customer is 15 miles (with -64dB signal). I think I can push that to 25 miles as doubling the distance takes 6dB.
this is the session stats with the antenna type (I think al of the Yagis are Cushman)

Just to let everyone know on this post that it was the 100 watt pacific wireless yagi’s. They just aren’t a quality yagi, as soon as we went anywhere that we tried the pacific wireless yagi’s and tried the cushcraft we got a solid connection immediately. Just a heads up for everyone who needs a quality yagi in nlos rural setting go with true cushcraft and stay away from pacific wireless which is a division of cushcraft that makes oem yagi products.
The model # on the Pacwire yagis is PAWYA9 9, 11 , 13dbi
http://www.pacwireless.com/products/YA9_DataSheet.pdf
Glad you solved your problem.
What was the Part Number of the Yagi that worked?
Here is the link to the yagi that we are using with great success.
