Antennas

From Entuura

The ASUS WL-500G Premium has "one external dipole antenna, Reverse-SMA antenna connector".

ASUS markets an antenna called WL-ANT168 with "RP SMA Plug (Quick)".

This page explains reverse polarity SMA. I checked at Media Markt, it seems the industry standards for consumer-grade wireless is this RP-SMA. For instance, the Linksys 7dbi omni antenna has the same RP-SMA connector on the antenna that the ASUS omni came with.

Some consumer devices (probably older?) come with RP-TNC, so many antennas come with a converter.

Finding a converter from RP-SMA to N-type would be necessary to use professional-grade antennas, which typically use the N-type connector.

6 dBi and 14 dBi panel antennas are available, but the prices on the 14 dBi panels are sky high, 220 SFr.

Topd has a panel antenna available for 100 SFr. It is indoors/outdoors, 10dBi I think. It has an N-type connector.

US Robotics has a nice intermediate model, at 9dBi with RP-SMA for 70 SFr.

This thread talks about problems getting the chipset to use the extranal antenna: http://forum.openwrt.org/viewtopic.php?pid=58703
