You can look for omnis with downtilt built in as well if you must go with higher gain and must use an omni.

Avoid the high gain 15dB omnis unless you know what you do and design system right. There are cases where a high gain omni is well suited but more then likely a 12dB omni would work as well if not better. You want to make sure your signal goes where your clients are not send the main portion above them where it does no good. /Eje Sent via BlackBerry from T-Mobile -----Original Message----- From: "Rick Harnish" <[email protected]> Date: Mon, 23 Feb 2009 08:47:51 To: 'WISPA General List'<[email protected]> Subject: Re: [WISPA] tower issue Actually, I disagree with Marlon on this one. The higher the gain on the antenna, the narrower the beamwidth. Therefore, many times your main lobe is shooting over the top of your clients. We have had better success with lower gain omni's because the beamwidth is wider and more usable signal reaches the client radios. I guess Marlon is correct if he means that the main lobe is shooting above (up) the clients, if that is what he meant, then he is correct.

With respect to direction, what's the difference between between a high gain unit and a lower gain unit? -RickG On Sun, Feb 22, 2009 at 10:34 PM, Marlon K.
