Sandman77 Posted December 15, 2012 Share Posted December 15, 2012 Today I found with the iPad a open WLAN 200 m away from my house! How high are the chance to catch the signal with a big outdoor WLAN Yagi antena over this distance? Sent from my iPhone using ThaiVisa app Link to comment Share on other sites More sharing options...
thaimite Posted December 15, 2012 Share Posted December 15, 2012 (edited) I suggest you buy yourself a can of Pringles, and then Google the word Cantenna I believe the flavour is not critical to the design.

monty Posted December 15, 2012 Share Posted December 15, 2012 Depends on obstructions between you and the wlan. Microwaves (such as wlan uses) penetrate solid material very badly. Especially wet stuff such as tree/plant leaves. If no obstructions in the line of sight, many hundreds of meters. If there are obstructions such as walls or trees, likely even the best antenna will not help you! Link to comment Share on other sites More sharing options...
Deke Posted December 15, 2012 Share Posted December 15, 2012 How would you connect the antenna to the IPad? Link to comment Share on other sites More sharing options...
Sandman77 Posted December 15, 2012 Author Share Posted December 15, 2012 Hi it is a USB antenna connected with the Yagi! In Europe the Max allowed sending strenth is limited by law! I found a dealer in hk he offer a antenna that proberprly have a little bit more power the description says up to 4 km range!

Pushit Posted December 15, 2012 Share Posted December 15, 2012 Sounds kind of parasitic, but I guess that's a sign of the times. Why not "Man Up" and get your own ADSL connection..?? Not possible, tether you phone. Link to comment Share on other sites More sharing options...
SeaVisionBurma Posted December 16, 2012 Share Posted December 16, 2012 I suggest you buy yourself a can of Pringles, and then Google the word Cantenna I believe the flavour is not critical to the design. or even google 'wi-fry' and look at images....

JakeBKK Posted December 17, 2012 Share Posted December 17, 2012 (edited) There are two basic rules to follow: 1) LOS Line of sight. YOU can see the antenna / router / wth 2) Fresnel zone - imagine a football (American) shaped space between the devices. In that space should be empty. also you need to enhance the aerial on both sides of a link. I like the frying pan, but actually an old satellite dish will do a better job !
