I just bought 2 P180 antenna to use for my line6 XD-V75 system. I am using six XD-V75 for a church in RF2 mode. I put the antenna on mic stands and raised around head level. I put them side by side pointing to the stage from right side of the stage. The "front" (which is written on the fin) side of the antennas are pointing to the stage. It has been working fine until 3 weeks ago, ever since we installed a new wireless alarm system, the signal has been dropping out constantly on 4/6 of them. Now, I moved 1 of the antenna to either side of the stage with distance about 15 feet to the center of the stage l -----O----- l like that.
I also have tried to use RF1 mode on all of them, but it makes the sounds distort so much that we decided to revert back to RF2 mode. I boosted the antenna to 23db and the mics are on high power. May this be a problem to the distortion?
We also only have 2 Wifi on our church with both 2.4Ghz and 5 Ghz.
