first, try to source the noise, it could be something as simple as a tech AC router somewhere on premise, at leasy do a sweep 360 degrees to see if you can locate the direction of the noise. If youre able to move your gear and there is structure you can get between you and the noise that helps because you eliminate it without adjuncts on the device. If its coming from the same direction as the other end of the link, I dont think there is alot you could do.
If you have the room for a radiowaves 2' HP antenna those knock down a ton of interference, we have been putting rockets on them with really good success, but its an 800 dollar antenna the last time we got one and that was a deal. You could also try splitting out the chains to separate antennas to see if you get some diversity. We had a radiowaves on a ptp 500 with noise on one end that we couldnt get resolved. We switched to seperate 1' Alvarion antennas with 6 foot verical and 2 foot horizontal seperation for no good reason other than they were laying there and for whatever reason we dropped power but the spectrum cleaned up, I suspect it was the direction of the interference and the fact that the two panels arent probably completely aligned with each other. You can also deploy a massive EMP and take out all sources of interference On Fri, Jul 3, 2015 at 1:17 AM, Rory Conaway <[email protected]> wrote: > On one of the buildings we are on, we used Jirous because of the > integrated shroud.
