I want to be a volunteer for ADS-B receiver. My apartment is on the second floor and the roof is 25 meters away from me. So I need longer H155 Coax cable. First, I read the equipment instruction and it is written that cable length have to be max. 10 meters. Do you think is that a problem? Second, If it is not a problem, how can I provide the longer cable? I searched on the net but this cable is really hard to find.

Thank you!
