Piercing and Accessories

2 November 2008

I'd like to be able to connect my note-book computer to a better antenna than those built into it.

I could drill a hole in the case, and mount an RP SMA jack there, connected to the internal Wi-Fi card. The patch cord that I would use fot this would cost me $20.50.

An alternative would be to get a new USB or PCMCIA[1] Wi-Fi adapter with a built-in external antenna connector. Setting aside units that I fear would be even cheaper than they are inexpensive, it appears that an adapter with an antenna jack or jacks would cost at least $40, and then not support the forthcoming 802.11n standard.

Thus, basically, if I bought one of these Wi-Fi adapters, then I'd be paying $20 or more to avoid drilling a hole in the case of my computer, and for the convenience of not having to open-up the case whenever I wanted to switch to-or-from the internal antenna that would be disconnected to enable the RP SMA jack. (A patch cord with bulkhead U.FL-R connector instead of an RP SMA jack would spare me that latter awkwardness, but I've not found such a cord.)

[1]I don't much like the idea of surrendering the PCMCIA slot, as I only have one; but I have six USB slots, and have never used more than five at one time.
