Re: [WISPA] FM tower co-location
I have a 2.4g Cisco AP and a 5.8g MT backhaul link on a FM tower at 99.5mhz. My gear is at 230' of a 300' tower. The FM array is 10 bays that is fed by 50k watts, and is only about 15' above my AP and BH links. The Cisco is basemounted and the MT radio is on the tower at 230'. No problems what-so-ever.

Re: [WISPA] FM tower co-location
Yeah. It's, by far, my most troublesome site. Not all the fault of the FM system I'm sure. There are 3 or 4 competitors only a mile away. And my antennas have to mount behind another tower etc. But the general noise there is so high I have to take my volt meter outside of the building in order to get an accurate reading. I hate being up there! I'd much rather have two other systems with no other users in the area than one like this. laters, Marlon (509) 982-2181 Equipment sales (408) 907-6910 (Vonage)Consulting services 42846865 (icq)And I run my own wisp! 64.146.146.12 (net meeting) www.odessaoffice.com/wireless www.odessaoffice.com/marlon/cam - Original Message - From: Chadd Thompson [EMAIL PROTECTED] To: WISPA General List wireless@wispa.org Sent: Tuesday, January 24, 2006 6:06 PM Subject: [WISPA] FM tower co-location Curious if anyone here has co-located on an FM tower?
