    Default SRC vs ???? card comparison.

    I got the SRC card and I am trying to compare it to other cards. Here is my comparison to the WT511G.

    SRC
    Antenna PWR Reading
    5 dbi Whip 10
    7 dbi Omni 14
    8 dbi directional 18

    WT511G
    Internal antena 11

    Now, my question here is why with a 5dbi antenna I have less power reading than with the internal antenna. What are your readings? If they are similar at least I know Im not that messed up.

    Thanks!

    PS - This is the infor from the antennas Im using

    UBIQUITI SRC 300mW Cardbus with Clip on Laptop Antenna
    Mini 2.4GHz 2dbi Laptop MMCX Antenna
    7dBi 2.4GHz Mobile Antenna
    MM-110N Vehicle Magnetic Mount - Large 4" dia, 10' N Female Cable
    2.4GHZ MOBILE PATCH, V-POL 8DBI W/SUCTION CUP BASE
    60 inch MC Card to N Male Pigtail LMR-100A

    What are you using for "power reading"? From my experience, I've noted that Linux drivers are not accurate in how they represent received signal for a number of cards / chipsets.

    I recommend taking your readings with the Windows client card utilities that come with the respective cards and see if things don't make a bit more sense.

    Pay attention to two factors :
    antenna producents show antenna powers too optimistic , they usually add +1db.
    You have loss due to long cables 50 inch -> 1-2 db , and 0,5-1db loss on MC screws and N screws.
    Use that 12 inch pigtail no longer , check the connections and use better antennas, so far the results won't be any better that Netgear.
