The numbers work well for a link. You can use calculators at YDI (http://www.ydi.com/calculation/som.php) to show that a link will work (or not work) with whatever power & antenna you have.
However, technically, 200 mw Radios into a 24 dBi antenna would not likely be legal. 200 mw is 23 dBi, and with the 24 dBi antenna, you're transmitting with 47 dBi, which is over the legal limit. Of course, you'll also loose a bit in cables and connectors depending on where your radios are, but if your radios are up the tower and wired directly to the antennas, then you'll be over limit. My recommendation would be to use YDI's great calculators to figure out what's legal and will work well. :-) - Todd Chamberlain ----- Original Message ----- From: "Chris Barcellos" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, February 03, 2003 4:22 PM Subject: [BAWUG] 25 mile link questions > I am in the process of doing background research for a 25 mile link that > i want to build between my home, and my place of work.
