Horns also have excellent F/B ratios and tight beam patterns with no side-lobes, so you can sometimes get away without using any guard band, depending on physical spacing and coverage overlap.** > > Do we need to enable "colocation" mode and choose a front/back sector?  Isn't that just for frequency re-use? > > **No, you only use colocation mode when sync'ing with PMP100/PMP450 radios. No, you only choose front/back sector modes when you're using back to back frequency reuse on two radios.** > > * * * --- _[View the full topic](https://community.cambiumnetworks.com/t/overlapping-sector-coverage-on-epmp-3k/66054)._
