You have to be aware of fresnal zone incursion.  I suspect that is why you are seeing poor performance on your current link.  Go to the calculators on the YDI site and run the numbers.   JH ----- Original Message ----- From: Oliver Leamy To: [EMAIL PROTECTED] Sent: Wednesday, June 11, 2003 1:21 PM Subject: [smartBridges] Height of Mast? Hi,   I have a need to connect three islands together.  Am going to use AirPoints and 20.5dbi mesh antennas.  On recent email discussions I�ve noticed that most people are using masts and the antennas at 100 or 200 feet.  For our installations, we will have to use residential premises.  There is a clear view between the locations.   Is there a reason why people were using 100� masts and does anyone think that I will have problems simply using the rooftops when there is no obstructions in between.   Oliver Leamy   Ogenek Teoranta, Ballingeary, Macroom County Cork +353 (26) 47808 ; +353 (86) 8337664
