    This article is pretty pointless to focus on Apple. Unforuntately clueless people will read it and assume that in order to use wireless they'll have to drill and void their warranty. The fact is there are plenty of other products for which none of that is necessary.

    The first time /. ran one of these "Mod your Airport" articles however many years ago it was cool but the wireless product landscape was very different then.

      My office got a shiny new "Airport Extreme" about two weeks ago. Not only does it have a built in print-server, but it also has an external antenna jack. I wonder how many Airports were returned to Apple service/repair with hole drilled in the sides before the company decided to spend the $0.07

      Sorry you feel that way, it's true. I just happened to have one and what's nice about it is that because it's round with a flat bottom, you can stick a pigtail on it and have a nice solid N type coaxial connector on the top.

          There are two airport extremes, one with a modem and an antenna port (for for 249 [apple.com]) and one without the two (for 199 [apple.com]). Which never made sense to me, I would think the user who wanted the antenna, would be the one who connected the airport to the LAN, and wouldn't ever use the modem.

    Based on the laws in the US, and my understading (I am NAL), because of the part 15 the antennas are illegal because they have to be certified good by the FCC as well as the unit itself which has been modified from the original spec. Article [isp-planet.com] talking about this for wireless ISPs, but the part 15 would still apply to individuals I believe. While it is unlikely that they would randomly come across you this is always a good deterent:

    This is a pointless /. story.

    1. First of all, this 'airport', is really just an RG1100 with a different cover. Sure, you can connect antennas to it. But it's not a "MAC Only" think it's a "Windows thing" that just so happens to have MAC OSX drivers. Google on rg1000 + linux/windows. You'll find several java config tools. Moron.

    2. Anyone who really has the title 'wireless network engineer' would know that building homebrew antennas just isn't worth the time. most of them end up sucking, and it's MUCH cheaper to just purchase one online.

    3. Anyone who cared about the FCC regs wouldn't do this.

    4. To do real LOS tests, you want antenna systems with known gain & radial patterns.

    5. You'll want kistmet, as some other posters highly under-rated posted.
    • Just another note on point #2: if you're going to build yourself an antenna (which is perfectly doable if the topic interests you), be sure you do it properly. A poorly made antenna, not tuned for the frequency you're transmitting on, can reflect much of the RF energy back into the transmitter. This has the effect of slowly frying the amplifier circuitry in your equipment. It's still worth it to experiment, if you're into experimentation, but if you're going to be doing this a lot, or many times, buy a S

They were put up last June and are still up and working nearly a year later, with no signs of failure. They even survived one of the worst gales seen in the west of England for several years (100mph winds if I remember correctly!).
        • I didn't say this explicitly in my other comment, but there's an efficiency loss here too. If your antenna is reflecting a lot of the energy back into the transmitter, that's energy that isn't being pumped out into the ether. Build your antenna well, and your transmitting coverage area could increase dramatically over a similar, untuned antenna.
