Question - Linksys WMP110 PCI network adaptor
I found this adaptor and wonder if it is of any use to me. It only
has one antenna (top) - the other antenna is missing. I do have a wireless router, and it would be great if my computer could connect wirelessly. No point trying if I need both or the other antenna(s). Thanks Big Fred |

The card is based on AR5008 chipset with 802.11N MIMO capability. That means it can use multiple antennas. But it would depend on how they were configured, as to what antenna has what function. For example, changing the RF section of the design, could support more or fewer antennas. I don't know if every antenna is a transmitter, especially when backward compatible with previous Wifi standards. The other standards might not have MIMO, and then one of the antennas might have more functions than the other. See "Number of antennas" for hints. http://en.wikipedia.org/wiki/802.11n If you look at the card layout, the upper antenna has a simpler set of surface mount components than the lower one. I'm *guessing* the lower antenna is a transmitter at the very least. If I only had one antenna, I'd connect the antenna to the lower connector, just based on the complexity of the "analog chain". http://images17.newegg.com/is/image/newegg/33-124-297-Z03?$S640W$ But I would also connect a terminator to the other, open connector. It's just the kind of guy I am. You really need to find out the connector type, available on the face of the card. They do make replacement antennas, but they have caveats. For example, this pair (about $25 when on sale and probably not worth it), are omnidirectional in the horizontal plane. These extend the gain, *on the same floor*, but would make it harder to reach a wireless router in your basement (below you) or on the second floor (above you). So the higher gain, is a lobe pattern extending in the horizontal plane. That's what one reviewer of this product, claimed. http://ec1.images-amazon.com/media/i...L000069509.pdf You'd search for an antenna, with matching connector type (as the connector type, also implies a characteristic impedance - one connector type might suit 50 ohm usage, another type 75 ohm usage and so on). Your two connectors could be "RP-SMA" but I've lousy at identifying those things. If this photo had been on just a slight angle, it might have helped. Antenna kits come in a number of different connector types, like maybe TNC, so it's a jungle out there. http://images17.newegg.com/is/image/newegg/33-124-297-Z02?$S640W$ Picking up some little USB Wifi dongle, with integrated antennas (patch antenna right on the PCB), is another alternative. It all depends on how bad you want to connect to that router. For example, $20 and you're done... This is better than buying an antenna kit, because it's a whole product and ready to go.
