Scott: Did you put up the sector antennas yet? That is your best long term solution along with your users using directional antennas, but you already knew that. SuperPass makes some panels with high front to back ratio's, and that is what you need to be looking at. (although with a metal plate you could do the same thing with your existing panel's... the idea is to shadow your antenna from the WISP's antenna).
Also, did you try talking to the WISP? Almost without fail, the ones I have tried to work with start with Omni antennas and want to amp it up. You could talk with them and see if they would move or alternately go to the opposite polarity as you. I'm assuming you are vertical? Who knows, you might be able to make some money consulting for them and kill two birds with one stone in the process. Lacking that, I'm assuming you have already gotten some PR with the city regarding this? They might be able to exert some pressure if you can't work it out with the WISP. There really is no legal basis for either of you to supersede the other (i.e Part 15), although some WISP's have tried to use contract law against other WISP's for collocation problems. How far are your users from you AP and how far away is "darkersun"'s AP? It sounds like to me you are quite close to your users, so something must be amiss here unless of course they are in the same marina. All I see next to the Marina is Chavez Park. Seems to me you should have a massive signal to your users... certainly much stronger then someone off the marina or the park. -- Jeff King, [EMAIL PROTECTED] on 10/12/2003 On Sun, 12 Oct 2003 11:05:20 -0700, Scott Douglass wrote: >Folks, > >For a month now I've been operating a free WISP in the Berkeley >Marina (80211b <-> full T1).
