[MLB-WIRELESS] correct method of antenna connection

[Dan Flett]

Hi Graeme,

Your AP almost certainly has twin diversity antennas, not co-phased
antennas.  I know of no APs that use co-phased antennas, but all the APs
I've seen with two antennas are diversity.  And the software for those APs
allow you to select which antenna is to be used - left, right, or diversity.
Some even allow one jack for rx and one for tx.  So just make sure you don't
set the software so that the AP is trying to use a jack with no antenna or
load attached.  Your only problem with SWR will depend on how skilfully
you've made your antenna.  Something even the most experienced antenna
homebrewers on this list have to deal with! :)  A lot of precision is
required when making antennas for 2.4Ghz.

Hope I've been a help,

Dan
