Optional antennas and 802.11n draft routers

Discussion in 'Wireless Networking' started by Lorenzo Sandini, Apr 30, 2007.

  1. Hello,

    I previously used a D-Link DGL-4300 router, to which I had attached a
    semi-directional DWL-M60AT antenna, with good results across the house,
    even on different floors, much to my surprise. That router accepted only
    one antenna unfortunately.

    The antennas on the D-Link DIR-655 can be removed, and anything with a
    SMA connector can be attached. Although D-Link claims this router has
    "better coverage", the signal was just invisible downstairs with the
    default 3 tiny white antennas, so I replaced two with DWL-M60AT spare
    antennas, and the middle one with a 5dB omnidirectonal from an SMC
    wireless NIC, and the coverage is now good everywhere.

    Is there anything special to verify before attaching an antenna to this
    router, or will any 802.11b/g antenna be compatible ?

  2. Hi
    If you get better results then use it, electronically (impedance wise) it
    would not harm the Wireless output.
    In theory part of the advantages of the 802.11n is the product special
    Antenna arrangement. I guess on some devices a good 5dbi antenna can
    compensate for a mediocre 2dbi MIMO.
