I don't know what equiopment you use... but... here's a scenario... 20 dbm radios... 15 db panel on one side and a 32 db solid dish on the other. At 15 miles, you should have a -68 signal. (Araya's link calculator says this) You're WELL within the P2P eirp rules for 5.8, and at -68 you should be able to use a star-os or mikrotik or other similar based link at around 36Meg data rate.
My stuff will stay pretty much at 54meg data rate at a -68, and even serious weather fade should keep you at 24Meg or above. Workable? pacwireless sells the solid 32db dish for 270 online. I sometimes use Compex 23 dbm a/b/g radios, for the power at 5 ghz, and they cost what I used to pay for CM-9's. ----- Original Message ----- From: "Mark Nash" <[EMAIL PROTECTED]> To: "WISPA General List" <[email protected]> Sent: Saturday, April 21, 2007 4:28 PM Subject: [WISPA] 5GHz Amps > I'm needing to do a 14-mile link at 5.8GHz.
