Hi all, Yeah bassicly I currently have a normal
PCI wireless card connected via SMA conector to a
15Dbi hawkins antenna I which can be seen on
the link below:
www.zitech.dk/_gfx/products/280570_200x160.jpg
I use it to connect to my friends network, he
lives accross the road... roughly 300 meters away
but there is some traffic going by the road
however I still remain at 60% signal and he is
on 8MB broadband so all in all its not too
bad and I cant complain but he refuses to put
up an antenna at his end ive asked!. But anyway
I was looking on ebay and I ended up buying
a Yagi 19Dbi antenna just to see if there is
any difference at all becuase it was quite cheap
from poland... can be seen on the link here:
[]
but anyway I just wonderd if there is any
reviews on the Yagi 19 as I cant find any,
also if anyone has one what are they like? i.e
do you think it will have a better signal/range
than my current one? thanks alot

Hives,
The Hawkins antenna looks like a corner reflector.
Like the yagi, they are fairly narrow band. I'm
assuming you're in the 2.4GHz band. Ideally, between
2.4GHz and 2.4835GHz it would be best to use an
antenna with at least a 5% bandwidth. However,
wider the bandwidth of the antenna it's generally
more expensive. It's easy and cheap to make a
narrow band antenna. Say, 1.5% bandwidth. If you
are going to create a link between these two
antennas I recommend you play with the channels to
find the sweet spot. Generally, antenna
designers put the sweet spot somewhere between
channels 5 & 7.
