PLEASE NOTE:
As a result of more stringent legal regulations and judgements regarding product liability, we are obliged to point out certain risks that may arise when
products are used under extraordinary operating conditions.
The mechanical design is based on the environmental conditions as stipulated in ETS 300 019-1-4, which include the static mechanical load imposed on
an antenna by wind at maximum velocity.
Extraordinary operating conditions, such as heavy icing or exceptional dynamic stress (e.g. strain caused by oscillating support structures), may result
in the breakage of an antenna or even cause it to fall to the ground. These facts must be considered during the site planning process.
The installation team must be properly qualified and also be familiar with the relevant national safety regulations.
The details given in our data sheets have to be followed carefully when installing the antennas and accessories.
The limits for the coupling torque of RF-connectors, recommended by the connector manufactures must be obeyed.

MOUNTING INSTRUCTIONS
ISTRUZIONI DI MONTAGGIO
N.B.: Before assembling the antenna, remenber that the waterholes on the
square bar and on the element in position No 2 must be turned downwards.
Elements in positions No 1 (long one) and No 3-4-5-6 (short ones)
These elements must be fixed to the square bar by means of the metallic threaded
block, screw, spring lock washer and large flat washer.
Make sure that the two teeth of the block are correctly inserted in the seats of the
element so to prevent its rotation after fixing it to the bar.
N.B.: PPrima
rima di iniziare il montaggio, tenere presente che i fori di scarico della
condensa sulla barra quadra e sull’elemento in posizione 2 devono essere
rivolti verso il basso.
Elementi in posizione 1 (lungo) e 3-4-5-6 (corti)
Questi elementi vanno fissati alla barra quadra per mezzo del blocchetto metallico
filettato, vite, rondella elastica e rondella piana larga.
Assicurarsi che i due dentelli sul blocchetto siano correttamente inseriti nelle cave
dell’elemento al fine di evitare la rotazione dello stesso dopo il fissaggio.
Element in position No 2
It has a threaded hole and must be fixed to the square bar by means of the screw,
spring lock washer and large flat washer.
Elemento in posizione 2
Esso presenta un foro filettato e va fissato alla barra quadra per mezzo di vite,
rondella elastica e rondella piana larga.

MOUNTING INSTRUCTIONS
ISTRUZIONI DI MONTAGGIO
Mounting plate
Fix the antenna mounting plate to the end of the square bar by means of the screws,
nuts and washers.
Use the holes in the square bar according to the required polarization (horizontal or
vertical).
Stop the unused holes with the plastic plugs.
Piastra di montaggio a palo
Fissare la piastra per il fissaggio a palo dell’antenna alla estremità della barra
quadra per mezzo delle viti e dei relativi dadi e rondelle.
Utilizzare i fori della barra quadra in base al tipo di polarizzazione desiderato
(orizzontale o verticale).
Chiudere i fori non utilizzati con i tappi di plastica.
Pole mounting of the antenna
Use the two U-bolts inserting them in the holes of the plate and fasten with flat
washer and two nuts.
Montaggio a palo dell’antenna
Utilizzare i 2 cavallotti inserendoli nei fori della piastra e bloccare il tutto con rondella
piana e doppio dado.
