-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.

Buildings, trees, superstructures and other objects, narrowing the horizon, make receipt difficult. It is recommended that antennas shall be mounted on pipe racks, i.e. vertical pipes fixed on a roof - in such a way appropriate mountings have been included in the kit for this purpose (5). Two antennas shall be placed at the distance of 1.5...2.5 m from each other.

-Before installation, the mounting pipes of the antennas are built up using extension cords (3) included in the kit and corresponding fasteners (4).
-Antennas must be grounded to ensure lightning protection! Lack of
-grounding is life threatening! Grounding can be provided by grounding the masts, on
-which are installed antennas, and, in addition, by grounding the antennas themselves onto the circuit
-lightning protection of the roof using the supplied grounding cables (11) (rigid;
-the supplied flexible cable (12) is intended for indoor use). On
-antennas, the cable is fixed with the same screw that is used to connect the antenna and
-extension cord.
-The antenna diplexer-amplifier (9) can be mounted both on the mast and on other elements of the roof with the help of the supplied clamp or some other fasteners.
+Prior to installation, all mounting pipes of the antennas can be extended with special extensions (3) included in the kit and corresponding fasteners (4).
+All antennas must always be earthed for provision of proper lightning protection! Absence of proper grounding is dangerous to life! Grounding can be achieved by grounding of an antenna mast on which antennas are mounted and additionally - by grounding of antennas themselves relative to the roof lightning protection circuit using supplied grounding cables (11) (rigid; a supplied flexible cable (12) is intended for indoor use). The cable is attached to antennas with the same screws applied to connect an antenna and extension cord.
-It is important that the side with connectors and inscriptions is on the bottom, since it is on this side
+The antenna's diplexer-amplifier (9) can be mounted both on the mast and on other elements of the roof using the supplied clamp or some other fastener types. 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.

+The feeder cable is connected to the adapter (8) by means of a ground contact. This contact is grounded with a flexible wire (12). Although the antenna is grounded, it is also important to ground the bottom end of a cable being connected securely, since a lightning strike taking place not too far away can induce current in the cable braid (like in a transformer) which can disable the receiver in case there is no path to the ground.

-Next, the SDR receiver is connected to the adapter using a flexible patch cord (7).
-After connecting the power, the station is ready for operation.
