Antenna Setup

kyoung1033 · 06-02-2005

I have a D-Link wireless router that is in one house at my lake front property. Currently, in my other house, approximately 1000 feet away, my computer cannot pick up any signal. There is a house between the two but I could angle the antenna to achieve line of sight. The closest I can get to the house with the router is approximately 900 feet by a tree outside. In order to get a better idea of my setup, I have attached an aerial photo with places marked and an approximate scale. What antenna (dBi rating, etc.) using an Orinoco PCMCIA card should I use to get a decent signal? Thanks.

PS- Sorry for posting such a large image last time.

What am I doing wrong? I can't find answer anywhere. What am I missing from that link you gave me?

If you are asking for help with a wireless link the following information will help.

1. Have you calcuated your link budget, SOM, fresnel zone? Many of the caclulators are available online. (please post your numbers).

fresnel zone radius- 10.14 ft
Free Space Loss- 89.8 db
link budget- 17 db

I don't know if these are correct- I'm kind of confused about the calculations.

PS- The reason I posted is because I have no idea about what I'm doing so that is why I didn't post calculations originally. I would appreciate just an approximation. Thanks.

Any chance of a picture from router antenna to destination antenna?

What are your coax losses?

Do you have proper fresnel zone clearance?

Next to ARRL, this is a great resource when dealing with radio links.
