    WIFI aerials.....what to do with them?

    I know it sounds childish, but HOW IS BEST?

    My Vigor 2600 has 2 aerials. Do they work best parallel? At angles aways from each other?

    Whats the story, morning glory?

    away from other sources of electrical interference.

    I have a feeling each one is for a different band

    I could be wrong but as i have a laptop that has a horizontal aerial, i alsways set them horizontal on the router as well. I don't know if the direction makes a difference or not.

    Its called polarisation and it does make a difference .

    Vertical polarisation is the most common and with a dipole (plain stick like) aerial that is acheived with the aerial sticking vertically up. A dipole gives a roughly doughnut shaped radiation pattern with the dipole sticking up through the hole in the middle. So with this kind of antenna vertical polarisation generally gives the best coverage. Having different antenna polarisations (say horizontal and vertical) between two radios on a wirless network will certainly have a negative impact on signal strength.

    Ive always had one horizontal one vertical, as I was told this gives maximum coverage

    At the frequencies involved, the two antennas are a significant distance apart in terms of wavelength, so that the phase between the two transmitted and received signals is different. This helps cancel out the effects of multipath trnsmissions (think of ghosting on analogue television pictures). Changing the orientation of the antennae will make little difference - keep them both near to vertical, at about the same angle.

    In the average house its so hard to gage radio efective-ness, just remeber that DECT phones, fridges, freezers, microwaves, can all course problems.

    I would just adjust them until you get best signal at the places you use the wireless pc/laptop.

    Be it horizontal, vertical, etc.

    There may be a setting in the router to change the Tx and Rx Antenna's to left/right/auto, but I haven't tried to see if it makes any difference.

    It may be useful to run netstumbler or something similar to help decide where the antenna's are best.

    I just leave them at the angle that my highly trained technician (cleaner with duster) leaves them.
    Not around too often!

    I had an issue with my coverage so I went the whole hog and replaced my antenna with the following item which jumped the signal in the garden from 2Mbps to 54 Mbps and now I can access the Web at the end of the road

    Oh - this is the antenna btw - not a bad thing at all

    Just had a look at the external antenna's on Scan. There is quite a difference in price, but what is the difference in performance?

    I assume the higher dBi the better?

    the Edimax does look like a good middle ground...

    IF it works with the same idea as wireless microphones (hey, Im involved with too many productions) having them set in a V shape gives best signal. Thats how I've got mine, not sure if thats just luck or not....

    Yeap thats generally the rule of the thumb with dBi

    I've quite a bit of edimax equipment and it does the job it says with no quibbles and I've not yet had 1 issue with any of their gear.
