Since the original post listed using CM9's, its possible that Antenna A/Antenna B selection is incorrect.

[WISPA] Big trouble with my first AP...
Gents & ladies, I have a difficult question for the list. I was testing my 1st routerboard/mikrotik ap this evening with terrible results. Let me give you the rundown of what I have and what has happened. Setup: 1 mikrotik routerboard 532 combo 3 cm9 minipci radios configured to 18 dbm via mikrotik 17.5 feet of lmr-400 from each radio to... 3 teletronics 19dbi horizontally polarized, 8 deg vertical beam width, 120deg sector antennas See the antenna here: http://www.teletronics.com/tant24sector19dbi.html My problem is that no where within 2 miles of the antennas can I get a signal better than -85 db. A senao in a rootenna mounted 50 ' away through a steel roof and pointing the wrong direction gives me -70 db on my laptop card?!? Is there something I'm missing. One other thing which might be the cause is that while I was setting up the mikrotik/routerboard I activated the 3 cm9 radios not realizing that they were set for the 5 Ghz band. They were probably like that for an hour until I got to that part of the setup. Perhaps something is wrong now or are the cm9's forgiving? Another thought I has is that the teletronics antennas are just not very good. Has anyone else tried them? Results? Is there a way to measure conducted output power at the antenna end of the coax? I could verify the radio output that way. Or a microwave field strength measurement I can do (spectrum analyzer?)? Any ideas guys Jason -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/
