Diameter is irrelevant and will not tell you frequency. The feed is determine the frequency.
If these are Pacific Wireless dishes then they are 5GHz assuming these are solid dishes since Pac never produced a 2.4GHz feedhorn for their solid dishes at least during the 6+ years we been one of their distributors. Only question would be if they are narrow frequency 5GHz or wideband 5GHz feeds. They been selling the wideband feeds for about 2 years now during this time the narrow frequency feeds have not been very popular. But even if they where narrow frequency 5GHz and you used it on the wrong 5Ghz frequency then they would still work except your gain would be down 3-4dB from what they could do. I cannot on top of my head recall how to determine the installed polarity of the feed but will go back to the warehouse to take a quick look to see how the feed needs to be installed for vertical and horizontal since it's impossible to tell by looking at the head of the feed on these dishes. / Eje -----Original Message----- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Josh Luthman Sent: Wednesday, October 21, 2009 9:40 AM To: WISPA General List Subject: Re: [WISPA] Identifying 2ft dish frequency Can you measure diameter and compare it with the 2.4 and 5.8 GHz dishes? Never thought about it but they would have to be different sizes.
