Assembly of the antenna RLA4G
The RLA4G is supplied with removed antenna elements.
Component set for an antenna RLA4G
The component set consists of the following parts:
•
4 pieces of antenna elements (each half of a loop), coaxial cable LMR-400 with TNC connectors of
reversed polarity (RP-TNC).
•
Node (connection) housing made of plastic with 4 RP-TNC sockets.
•
Amplifier housing made of bright aluminum with 4 RP-TNC sockets and normal TNC socket for the
antenna cable.
•
Stainless steel connecting rod with a M5 nut screwed on each end.
All parts are made of weatherproof material (resistant to UV radiation and moisture) and are IP65 dust and
waterproof after proper assembly. The amplifier inside the aluminum housing is designed for a wide
temperature range (no electrolytic capacitors, components with an extended temperature range). All
components, with the exception of the coaxial connector for connecting the TNC socket for the antenna
cable, are arranged in an SMD version on a circuit board and sealed with synthetic resin.
The amplifier housing is bare metal in order to achieve a high reflectivity against solar radiation. This
keeps the amplifier from heating up as much as possible on hot summer days. The housing consists of a
body in which all parts are mounted and a screwed-on base plate with an inserted seal. There are tabs on
the floor panel for attachment to any support elements (mast heads, beams, roof surfaces, ...). Fastening
must be carried out using suitable countersunk screws (wood, self-tapping or threaded countersunk
screws of 4 mm in diameter).
Caution!
When screwing the housing on, no forces may act on the tabs or the base plate (no "warping").
The mounting surface must be absolutely flat and level! If necessary, suitable supplements must be placed
to compensate.
There are 4 small holes in the bottom plate near the corners. They serve to equalize the pressure in the
housing in the event of major temperature changes, as well as to drain off any condensation that may have
