Wireless long range antennas

I've been experimenting with a couple of long range wireless 2.4 GHz
antennas, one 15 dBi and the other 18 dBi, and connecting them to my D-Link
WBR -2310 Wireless Router, and I have also tried a smaller 9 dBi antenna.
They all connect to my router properly and I am not using very much cable (3
feet of low loss cable). I am not getting any better of a signal with them
than I am with the original antenna. All of the antennas that I am
experimenting with are Omni-directional. I am sure they are connected
properly but I am simply not getting a signal boost for greater range. This
is very disheartening since I have invested quite a bit on these antennas.
Any suggestions or maybe something that I am missing. I have tried
different environments, different frequencies (other than those of other
wireless networks around me) but my signal range ahs increase noticeably
enough. Thanks, Bob

Hi
Could be a lot of things.
What did you use to record the signal strength being recieved. I use
netstumbler or other tools.
It may be the receive end that is the problem. Maybe the receiver in the
laptop can be replaced as a test.

Omni high gain antenna's tend to radiate as a
disk, could it be you are obove or under the
device you are connecting with?
Also, the 18 dBi antenna ( seems very high to me )
will have some "uptilt" iaw radiating not horizontal
but a fair bit upwards. It can help mounting it upside down.

Donut is more common term that is used for the radiation pattern,
of a omni-directional

My expierence is, putting the omnidirectional, horizontal, gives better
reception on a higher/lower floor, even on my atic, in my (old)
house..(if you're on the same level, put it vertical) i can imagine,if
you are in a house with much concrete walls, that this could block
radiation power, try to place the WiFi router at a more accessable
place, like near a stairwell, or in the middle of your house, or use a
(or more) range-extender(s), wired or wireless... try to get one, in
that case, of the same brand, as your WiFi equipment/router is.
