-Antennas (1, 2) should be installed on the roof of the building or in another place with the best possible view of the sky. Buildings, trees, superstructures,​ etc. that narrow the horizon make reception difficult. Antennas are recommended to be mounted on pipes, that is, vertical pipes fixed to the roof - for this, appropriate fastenings are included (5). Two antennas should be placed at a distance of 1.5..2.5 m from each other. If there are no pipes on the roof, it is technically possible to fasten them to the railing posts (if the rules for operating your roof allow this), or to specially installed brackets (they are cheap and freely available in any store that sells satellite dishes), or, in the case of a flat horizontal roof, onto a heavy metal sheet or frame with a pipe attached to it.+{{:​en:​image_11.png?600|}}

It is important that the side containing connectors and letterings shall be placed on the bottom, since a drainage hole is located in this location, being applied to remove condensation. The wires taken from antennas are connected to corresponding inputs of the diplexer-amplifier. It is important not to mix up the inputs. The 136-146 MHz band antenna is about three times the size of the 435-438 MHz band antenna. It is acceptable to leave one of the inputs non-connected. The feeder cable (6) shall be connected to the output of the amplifier. The feeder cable shall be routed to the installation site of a workstation.
