Aironet 1240 + 12 dbi antenna

[Christie Brinker]

                   Hey all,

I have a Cisco Aironet 1242G and an outdoor omni 12 dbi antenna. I hooked it all up to day  (antenna is connected with a 100ft cable). My signal is very disappointing. I have it behind a garage and can only get about maybe 75 foot away and the signal gets very weak.

Is there something that needs to be configured in the aironet? I have enabled external antenna and played with the settings. Is the 12 dbi antenna just too much?

What cable are you using?  Usually for that long you would use LMR 400 and or LMR 600 to reduce attenuation.  See this online calculator
