    Hi

    I am trying to set up a link with external antennas between home and work.
    distance is 8km and i wonder if there is some software i can use to align my antennas directly against each other?
    I use tomato firmware 1.25nd victek right now.

    I have 2 Hyperlink Technologies HG2419G-NF 2.4 GHz 19 dBi Die-cast Grid Antenna,

    Tips are VERY welcome :)

    That's quite a distance - do you have line of sight and use Yagi's? Use a telescope for aiming, and don't expect it to work when it rains?

    Sorry, I have no experience with the antennas you have, but I would like to know the length and type of the feed line you are using at both ends.

    You do not have much in the way of tx power and signal attenuation @ 2.4GHz in coaxial feed lines is pretty bad. I also suspect that the receiver sensitivity is less than stellar compared to the kind of equipment I have used (Satellite communications equipment in Ham Radio). For 2.4 GHz and up, we tended to use transverters located at the antenna to down convert the frequency to something less sensitive to feed line losses, such as 4xx MHz and we could use significantly more power, but then the range was quite a bit more as well.... :biggrin:

    With the length and brand/type of cable you are using, we can check the charts and see just how much signal is being lost in your setup.

    To accurately aim your antennas, you would need some sort of signal strength measuring device.... perhaps one of those tv dish aiming devices would work, though I'm not sure about Sat TV frequencies.... I've been out of the loop for a few years now.....

    Regards
