RE: [WIRELESS-LAN] Extending an external antenna

Title: Extending an external antenna

We’ve successfully used microwave cable for b/g/a for shorter distances, up to 50’ on LMR400 but I’d recommend LMR400 up to only 10’, LMR600 up to 50 or 75’.  I’ve never tried anything that far but a panel antenna and perhaps LMR900 would be a way to go.  An omni will pick up a lot of noise and you will want to minimize noise especially given the distances.  LMR900 will work up to 6GHz.   Mike   - Michael Ruiz Network and Systems Engineer Hobart and William Smith Colleges   From: Lee Weers [mailto:[EMAIL PROTECTED] Sent: Friday, May 19, 2006 11:42 AM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: [WIRELESS-LAN] Extending an external antenna   We have a situation in which we need to cover our baseball and softball fields wirelessly.  There is currently no infrastructure there.  What we are looking to do is put a high gain antenna on the football stadiums scoreboard.  There is a conduit that we can run some coax through out to the scoreboard.  My question is this: 1.  Can you extend an antenna from an AP 250 ft?  (That's how long it is to the scoreboard) 2.  What kind of coax do we need to use to do a/b/g? We would like to mount the ap inside of the building and then just extend the external antenna to the scoreboard.
