[ILUG] 802.11b?

You can get a 24db gain parabolic antenna for 50 Euros - Of course such an
antenna would be illegal in this country - unless you have a long piece or
poor quality "Low loss cable" (or not so low loss). 
The go down in price from here depending on the size/gain. (13db 20 euro)

These are the cheapest type of antenna (parabolic) and are sorta large
(depending on the gain you want) - but fairly adequate it seems for
"hobbyist". 

Some folks in Clare are covering 4-5 kms with these (not sure what size)
(with good LOS you could probably cover even more). 
(originally they were using some converted MMDS dishes). 

100 meters is nothing - you could cover this with a home made Pringles can
antenna's easily and you'd have fun doing it !! (google Reilly Pringles can
antenna). In fact one antenna and a base station will probably do it (but
I'm not sure)

I THINK you generally need to buy connectors separate, the buffalo (and most
others) use the lucent connector type - called a pigtail. These cost 35/40
euro either vbnets or stella sell these. 
You need to make sure you get the correct gender to match you're
antenna/cable. 
Pigtails are generally short and the antenna's are large so you're probably
going to need to buy some cable - if you make it up your self you'll save
money - this cable is generally expensive (but if you buy an antenna larger
then you need then you can skimp on the cable I guess). 

Note, you're going to need to 'mount' these things somehow and if you going
high you need to think about protection - NO not that kind - I mean
lightning.

P.S. the 13db's are square - which
