SOLUTIONS

Solution 1:

Antenna mounted in the

adjacent Tower leg.Without changing the

offset of the antenna.

Antenna side strut can

be mounted within

standard.

ffects of Wrong Installation:

1! Antenna is far from the tower.

"! #ore prone to tearing of mounting pole

due to wind pressure.

$! #ounting of side strut is impossible to

attain.

%! The I& cables' wa(eguide and grounding

cable are e)posed for greater wind

pressure and (ibration.

:- folloing the proper installation of the side strut and the right

offset! the risk of deforming! misaligning the antennas and trafficoutages ill be minimi;ed and be prevented in times of severe 1

harsh eather condition(

0la-s keep in mind to mount the side strut in parallel to antenna

direction for maximum stabilit-( 0nd if this can not be achieved! adeviation angle from its parallel position must be not more than '.o

in an- direction(
