LTE Biquad 1800 MHz

thingiverse

I couldn´t find a 1800 MHz LTE-antenna - they all where multiband antennas. So I decided to build my own. I found instructions on the following page. This is where I got the measures from: https://www.lte-anbieter.info/lte-hardware/antenne-bauen/bastelanleitung.php I took the "Bi-Quad 2,4GHz Bending-Template by SnakeP" and scaled it up to my needs. Then I reconstructed a pull-relief and added a round container to it to mount the antenna itself and to keep the distance of the antenna to the reflector. A aluminium-rod (20 mm) is used as a pole and I simply took hot glue to attach it to the reflector. The foot glued to something heavy gives a good stand. I´m quite satisfied with it. The gain is 3 to 4 dBi, which meens a doubling in signal strength. ### You need: - copper-wire 2,5 mm2 (1,8 mm diameter) take from 5 x 2,5 mm2 power line, just remove the isolation - antenna cable with connectors matching you LTE-device - rod (20 mm aluminium in my case) - something heavy to glue the foot to - a soldering iron - hot glue ### print Print the threaded parts with 0.1 mm layer height. Everthing else is fine to be printed with 0.2. I used PLA. For outdoor use I recommend ABS or at least PETG - and use a clearcoat to seal everything.
