Hi

I have been to http://www.jawug.za.net/ and have some inspiration.

I live in the cape and this is want I want to do.

I want to connect my house to my girlfriend’s house as a little project. :)

This is the hardware I was thinking about:

My House:

Linksys WRT54GL
and an Omni Directional Antenna (15dbi gain) (http://www.miro.co.za/stage/intranet/datasheet.php?id=49)

Her House
Linksys WRT54GL
and an 12 dBI Yagi Antenna

We are +- 800m from each other.

Will this setup work? If not what should I do.

The Omni Directional Antenna is so if other people would like to connect they can, but it's not a must.

Regards

Terence


(ps i know of Line of sight etc. will the hardware do the job...)
 
Rather get another Yagi or Sector instead of that Omni...

At 800m, 12dbi should be fine as long as you have decent LOS

i would agree don't do an omni.... think of all the kittens :p

omni's in a case like that are just not good for you or everyone else... be responsable dont use omnis

if the project grows which i hope and sure it will then you can change the antenna to suit the situation then... and if you asking the question but it's a waste of money to buy another antenna later... nah, you'll find a use for it once you get hook into wireless there is no stopping.

oh and you will get better performace from a yagi. we have a 3km link with a 12 db yagi and WRT on each side... gets 800-1000K
 
skydogs right use 2 directionals until you need the omni, then you can use the 1 directional at the new site.

There should never be a need for a 15db omni. If an 8db cant do what you want your doing something wrong. Remember 360 coverage = 360 noise
 
Besides, A little birdie told me that after running some tests on these popular 15dBi omni's, that they only exhibit arount 10dBi of gain anyway.
 
Thanks a little more info please...

Hi Guys thank for all your response.

I have read that so many people say don’t use omni use a sector antenna.

So my question is if I have a sector antenna will someone within the range at any level be able to pickup the signal.

E.g. someone sitting on is lawn with a laptop. Will he be able to pick it up?

Thanks

Terence

Your question is misleading "in range" automatically implies they can receive the signal. If the sector is on your house, yes you and your neighbor and so on will be able to scan and connect to your site. You will find even a couple Km's (LOS and height permitting) away you can receive the signal, but you will not be able to transmit back. If you can almost get it, try getting your girlfriend to kneel and place your left foot on her back, then with Amstel in left hand, with your right hand tilt the laptop 45 degrees away. If you fail, know that you still have the admiration of all your onlooking mates.
 
lmao @ nomdeplume. wheres about in the Cape are you mate?
