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.

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
