This antenna does NOT include cabling. You must select a length of cable from the list (for the ultra-low-loss cabling, we bundle the connector you'll need to connect the cable to your adapter). If you already have a compatible cable you plan to use (this antenna has an N/Female connector), you may select the "I already have a cable" option at the bottom of the list.

How much cable should you use? Unless you plan on using an amplifier as well, we recommend using LESS THAN 50' OF CABLE to minimize signal loss. The longer the cable you use, the more signal you lose. Mounting the antenna outside and reasonably high up is recommended, but using long lengths of cable for the express purpose of mounting the antenna higher up is NOT worth it - you will lose more signal from the cable than you will gain from mounting it up higher. For example, using a 20' cable and mounting the antenna at the roof line would be better than using a 50' cable and running the antenna high up a pole on the roof.
