external antenna on PCM350

Is there any way to hook up an external antenna to a PCM350? Under the plastic cover with the two LED holes, there is what looks to me like an antenna jack. I'd like to find a mate for that and hook up a short flexible coax cable with an "N" connector on the other end. This would be very helpful in doing site surveys, etc.

I know I could also get an LCM card with no antenna at all but I already have this card (a couple actually) and it would be nice to be able to test with either the internal antenna or an external one.

Another option would be to modify the card but I'm not particularly wild about that one....tempting though:

Re: external antenna on PCM350

I'm not going to tout another solution over Aironet, but for Site Surveys the Orinoco cards are very useful for two reasons:

1. They include an antenna connector (which is good, because they have less Receive Sensitivity, so they need more antenna gain)

2. Their survey utility monitors multiple APs simultaneously (which helps locate channelization conflicts and allows you to verify desired overlap)

The other device that is very useful is a Proxim RangeLAN 2 card to run a scan of the 2.4GHz band, a sort of poor man's Spectrum Analyzer.

The Orinoco card uses a different pigtail than Aironet LMCs, but the Proxim card uses the same MMCX connector. Let me know if you need help finding parts.

$400 worth of cards, pigtails and antennas will make your life A LOT easier.
