With the 27dB TX power and 34.4dBi dish on one side and 31dB dish on the other I get about 21dB of fade margin. Thats not very hot if you ask me.

AMD Phreak Please do the needfull Premium join:2003-12-14	Yeah recieve power is -58dB. I'm leery about having such a low fade margin though on a path like this in our mountainous terrain. I'll PM you Hal so we do not threadjack this post..

schj98 join:2003-05-20 Harrisburg, NC	reply to kf6ytc I currently run a Tranzeo TR-5Plus-N link with 32dBi dishes at 37 miles. Signal is -53dbm with a throughput of 15mbps TCP and 19mbps UDP. Link has been up for almost a year and a half with 0 issues. Of course LOS is key especially in a link at this distance. Run a radio mobile plot before your buy anything. Hope this helps.

Will Tranzeo Tr-5plus radios work with 32db dishes? Most of the 802.11a based stuff will do this, lock the throughput to something lower than the max to get a fade margin of at least 30 db for a reliable link. You can also look at the Trango T-Link 10 which will work as well.
