I had to google for recommendations to pass on to you, but found: |

|
| 18 |
I've had great results mesh networking with 15dbi omnis |
| 19 |
available from http://www.wlanparts.com. With line of |
| 20 |
sight I can connect to these from over 1/2 mile a way with |
| 21 |
my laptop. Watch your transmit power as with high gain |
| 22 |
antennas its easy to venture in to illegal power levels. |
| 23 |
See: http://www.rflinx.com/help/calculations/ Remember high |
| 24 |
transmit powers only increase range if both ends increase |
| 25 |
their power. In most cases increasing power does little |
| 26 |
good at just one end of the link. |

Indeed wlanparts.com would appear to be the kind of folks I had in |
| 30 |
mind (they look to me like the kind of people you could email for |
| 31 |
advice - if you were to email them the question you originally posted |
| 32 |
to this list, maybe they could suggest a replacement?) but it might |
| 33 |
also be worth searching openwrt.org & it's forum for aerial or antenna |
| 34 |
and take a look at few more of the results there (i.e google "aerial |
| 35 |
or antenna site:openwrt.org" will include the forums). |
