Re: [WISPA] Dual Pol Antennas
If you do a spectrum scan it shows signals of other APs in dbm. If you use have one as a station, it shows dbm on the main page. On an AP, if you show stations (list of associated stations), it shows a positive integer RSSI which I would presume is the same as SNR as it's definitely not dbm. (I am told to add -97 to it to get dbm) So you get dbm on the stations, on surveys, but not on the AP for the radios associated.

Re: [WISPA] Dual Pol Antennas
We do this with Motorola gear that is synchronized. Unsynched gear may not work well as the isolation between polarizations is not that great. One transmitter will be getting into the other receiver. It may be 20 dB down, but if it is coming out at +27 dBm it will still be hitting the input of the other unit at +7dBm. That is a powerful amount of interference. - Original Message - From: Joe Miller [EMAIL PROTECTED] To: WISPA General List wireless@wispa.org Sent: Monday, September 29, 2008 5:31 PM Subject: Re: [WISPA] Dual Pol Antennas Now for the 64 dollar question on dual pol antennas...Can one run 2 separate links using a Dual Pol Antenna pair.

Its ironic as heck, that trango can sell an entire AP radio and int DP sector antenna, for less than third parties sell a single DP sector antenna by itself. Thats still the missing peice of the puzzle in 5.x Ghz DP. Its Ironic as heck... Titltek can make a 4ft 900Mhz dual pol 90deg for under $700. But can't find a 2ft 5.x Ghz Dp 90 for less than a grand. The last few I did, I took my old Trango 5800s, drill holes in them for the pigtails, took out the SBC, and used them for the antenna. It was cheaper than buying an antenna. A couple vendors have represented that they can make them. But I don't see part numbers listed. I'd love to see these in the sub $300 range.
