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
