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. Personally never used or tested TT's 15-124 antenna but have sold a few of them with no complaints on it as far as I know. -----Original Message----- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Michael Baird Sent: Sunday, June 28, 2009 8:33 AM To: WISPA General List Subject: [WISPA] Antenna Performance I picked up a Teletronics 15-124 19db horizontal antenna for testing and deployed it in place of a Tranzeo 16db Horizontal (TilTek?), using same pigtail and radio. With the clients on this sector, the AP side is the same, but the CPE receive side seems to have suffered with this larger antenna. Nothing was changed other then the antenna, aimed to the exact same degree, tilted the same percentage of vertical tilt, and so forth. I'm thinking the antenna isn't very good, or it's VSWR is too low and I'm getting some power reflected from the antenna. Anybody have experience with this antenna, or these scenarios? I expected this bigger, more expensive antenna to gain all across the board. Regards Michael Baird ---------------------------------------------------------------------------- ---- WISPA Wants You!
