how can i setup a cisco yagi antenna

[albertldee]

i have a cisco aironet 1300 and a cisco yagi antenna that i'm trying to seek some help with installation

1. i want to keep the aironet inside the building and mount the cisco yagi antena on the roof it will require about 150ft of cable pretty expensive i was wondering i have a 200ft of RG59 coax cable can i use that with some N connector to mount the antena on the roof i know it's not the best option but temporary for 6 month

2 the cisco yagi antenna will be mounted about 25 feet from groud what's the average are LOS it will cover in feet

thanks
