John - several years ago using similar equipment we started receiving interference when we had an omni installed on a firetower with about 17 clients. To locate the interference, we had to power the omni down and use a sector antenna to determine which area / azimuth was "screwed". We wound up having to install sector antennas to 300 degrees of the 360 degrees because a cellular provider had installed a backhaul that was interfering in the direction their backhaul came from.
Another similar instance occurred when we were picking up inventory control systems a walmart was using - - 5+ miles from the site but nearly line of sight across a field. Raised our noise floor and took out good signal on 2/3rds of the customers - again - in that azimuth only. Similar solution - an omni no longer worked there. Omnis are great in a lot of areas when they work, but it only takes one slice / azimuth to ruin your day. I hope this helps.

They receive interference from 360 degrees. Most folks only use OMNIs in areas where the distance can be very short. You might want to post this question on the [email protected] email list. Just post something to that address and it will reply with info as to how to subscribe to the list. There are about 600 people there operating this equipment, the manufacturer's engineers hang out there too. Friendly bunch. -----Original Message----- From: WBMfg Website Sent: Tuesday, December 23, 2014 12:01 PM To: WBMfg Subject: WBMfg Website Comment/Feedback 12/23/14 12:01 PM john f ockert [email protected] 4174342384 we purchased your epmp Omni conversion kit. I followed the directions. I have great downlink modulation and capacity and quality from ap to subscribers but the uplinkf from subscribers to the ap is poor most of the time. it isn't interference and it isn't aming the subscriber units. is there something wrong with the Omni. we have one tower with sectors and decided that we would use an Omni on another to see how it preformed. so far not so good. have you seen anything else like this. any help would be appreciated.
