Antennas

I have a 15dbi panel antenna but I've moved to the back of the house and im not getting decent signal, would an omni help? And what kind of range can one expect with a decent omni?

Thanks

are you connecting to the panel with a laptop?

I have 2x netgear nics, wg311 v3 and wg311 t, 54 mb and 108mb , also have linksys wrt54g running dd-wrt.

Its my desktop that im looking for increased signal for, the panel is annoying since its directional, what kind of range can I expect for an Omni?

Im in an external room at the back of the property and its in a corridor so its kind of hard to get reception, wondering if an omni would help, surrounded by walls,electric fence,tree's. Its sucks , kind of hard to pinpoint signal with a directional in those circumstances

Thanks
J

omni will probably have less range then a panel. and your link quality may go down.

so you using a panel on your PC?
and what antenna is on your access Point

I would make small adjustments (say 5 to 10 cm at a time) on the position (and maybe orientation) of the panel and monitor the received signal. The signal path is very complicated, but there will probably be "hot" spots and not-so-hot spots.

I have noticed the above while playing around with a USB wireless adaptor trying to pick up a router on the floor above me and about 15 m down the hall. Rotating the adaptor and moving it around I found a "hot" spot where the connection is quite good.

I also have a Worldspace satellite receiver with antenna operating at about 1.45 GHz. I got no signal indoors but after moving it around I found a "hot" spot indoors where I get almost full signal strength through the roof. This is working through a roof made of flat panels of asbestos. Even works if the roof is wet...
The previous place where I stayed had a tiled roof and there it also worked.

A while back I struggled to pick up VHF tv, found the best spot, not on the roof, but 1 m away from the ground under the roof on the stoep.

So bottom line, be patient and really SEARCH for the best signal

From what I've heard of omnis, I'd rather use the panel, and try and move it around/aim to a different spot. If your not broadcasting, stay away from onmis
