1550 tri-band amplifier advantages: The Kilt is adapted to use the three frequencies with an omni-directional antenna for high gain, so we would come to a good solution because the signals can come from different directions so we avoid having to put an antenna for each place of receiver that signal, it would greatly simplify the installation process. This antenna comes with 11 meters of cable (50 Ohm) and N connectors for amplifier, external antenna Sticking to the technical specifications for this team to be able to install antennas inside a multi-frequent high gain Wall N standard connectors to ensure better results, the kit provides up to three (3) meters of cable as specified is the greatest distance that the antenna should be placed inside.
