The feeds used on the Pac/Laird 2" dishes is 8.5" long from flange to the bottom of the feed. The new wide band feeds are a flat looking disk 5.75" in diameter.
http://store.wisp-router.com/customkititems.asp?kc=DA5W%2D29&eq=# Shows a picture of the old "narrow band" feed it's about 2" in diameter. You can see a picture of the wide band feed at http://store.wisp-router.com/customkititems.asp?kc=DA5W%2D32&eq= It looks just the same on the 2ft dish even if I linked to the 3ft. If you need a wide band 5Ghz feed for the 2ft dish then this http://store.wisp-router.com/itemdesc.asp?ic=DA5W%2D29%2DFEED&eq=&Tp= Should work assuming the length of the arm is correct. (not that the picture is the old style narrow band but the item we have in stock is actually the wideband, guess I need to make sure we get the picture updated for this item). On the wideband if the N-female connector is up/down then you are set for vertical and if the connector is to either side your set for horizontal. On the old style feed the connector is straight back and there should be markings on the base if this marking is up/down your in vertical, side either side it's horizontal. I want to recall it's just a notch or circular depression (do not have any of those feed left so can not verify). / Eje -----Original Message----- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Mark McElvy Sent: Wednesday, October 21, 2009 10:22 AM To: WISPA General List Subject: Re: [WISPA] Identifying 2ft dish frequency I suppose the may not be pacwireless as I have determined they are 2.4 by hooking the up to a CM9 and when ap is in 5.8 I see nothing and when in 2.4 I can see.

Obviously it's 5GHz! Polarity is normally done with an arrow sticker on the base of the feedhorn. Of course if it's been out in the weather it's long gone.
