Nothing was changed other then the antenna, aimed to the exact same degree, tilted the same percentage of vertical tilt, and so forth.

I tested multiple tilt's as well, between 0-1 degree was the best on the CPE side. Regards Michael Baird First thing that comes to my mind reading your post is that you installed a higher gain antenna which means your vertical beam is going to be narrower (sometimes higher gain is not always better). Being that you installed the antenna with the same down tilt angle your missing the mark because you have a narrower vertical beam. As for the VSWR nothing really considered too low. If your VSWR is higher then 1.5:1 then you have a problem for sure.

Re: [WISPA] Antenna Performance
I have to wonder if some of the client radios may be pointed at sidelobes rather then the main beam. One thing you see between the two antennas published patterns is the lack of pronounced sidelobes on the teletronics. Regards Michael Baird Gain only comes from narrowing coverage with antennas. If there are both 120* antennas you can't have HIGHER gain with GREATER coverage It takes half the coverage area go give you twice the power (3DB of gain). http://www.odessaoffice.com/wireless/antenna/how_to_pick_the_right_antenna.htm laters, marlon - Original Message - From: Michael Baird m...@tc3net.com To: WISPA General List wireless@wispa.org Sent: Sunday, June 28, 2009 2:32 PM Subject: Re: [WISPA] Antenna Performance Not ,the same downtilt angle, same percentage as the old one.
