We are an isolated ranch in the hills with several buildings sharing one satellite connection. We have an external omni with directionals at the desktops using d-link routers. Many dead spots where we would like people to be able to use laptops. Can with linksys wireless-n be set up to use external antennas? How long a cable? Thinking of using an existing antenna tower. No help from this site, but we made it work: Connected the linksys wireless-n to the satellite, connected two external omni's through two of the ports with D-link access points and gave them separate channels. Get the direct n- coverage inside the building, outside at the other cabins, they choose whichever antenna gives them better coverage -- regular g.
