Mounting and Operation  

 

AD511 should be mounted with an unobstructed view of the sky. An aluminium 
bracket with V-bolts is provided to attach the antenna to horizontal or vertical 
masts or spars up to 60mm in diameter, 

figure 2

. The bracket is shipped inverted 

on the end of the AD511 antenna and should be detached, turned over, then 
repositioned either to the centre or end of the antenna case as required using 
the mounting holes in the base. 
 
 
The coaxial down-lead is attached to the N-type connector on the underside 
of  the  antenna, 

figure  2

.  Wrapping  the  connectors  with  self-amalgamating 

tape  is  recommended  for  permanent  installations  and  the  cable  should  be 
taped or strapped to the spar as appropriate. 
 
 

AD511  antenna  supplied  with  coaxial  down-leads  must  be  used  with  the 
accompanying  AD510-40  DC  Power  Break-In  Box  (figure  3),  which  accepts 
+18V to +36V DC at 500mA. The down-lead must not be shortened by the user.

 

 
 
AD510-40  Power  Break-In  should  be  positioned  close  to  the  telephone  base-
station  or  handset.    The  coaxial  down-lead  is  then  attached  to  the  N  type 
connector on the AD510-40 (

figure 3

 & 

figure 4

).  

 

 

Earthing:  -  the  AD-510-40  power  breaking  box  is  provided  with  an  earth 
terminal.  The box should be earthed via this connection with a short earthing 
lead connection to the system earth.   

 
 
Connection between the telephone and the AD510-40 is made with a coaxial 
cable terminated with TNC connectors. An adapter is provided with the Iridium 
handset,  which  enables  a  TNC  terminated  cable  to  be  attached  to  the 
telephone. AD510-40 case has drilled flanges to enable permanent fixing. 
 
 
A 3m flying lead for the AD510-40 Power Break-In Box is provided for connection 
to  the  DC  supply  (+18  to  36  v  DC  at  500mA),  which  can  be  trimmed  (or 
extended) if necessary. The red wire is connected to supply positive, whilst the 
blue  wire  is  for  either  an  isolated  or  grounded  negative  supply.    AD510-40  is
