Introduction
Iridium telephones were originally designed to operate with a passive antenna,
either an element attached directly to the handset, or a remote aerial
connected with a short length of coaxial cable. Unfortunately, a signal loss of
more than 3dB in a remote antenna’s connecting cable degrades
performance due to attenuation of both the received and transmitted signals.
A 3dB loss corresponds to approximately 10m of RG213U or 3m of RG58U
coaxial cable, lengths that clearly restrict the mounting options for the antenna
using standard down-leads.
AD511 active Iridium antenna (figure 1 & figure 2) is designed for use with up to
160 meters of coaxial cable terminated with type ‘N’ connectors, and with
coax lengths starting from 27meters – subject to AST advice.
Designed for harsh environments, the AD511 consists of two RHCP dipole
antenna housed within a 4mm thick GRP radome mounted on a common
base. One antenna is for signal transmission and one for reception.
AD511 has a linear power amplifier within the base and connected to the
transmitting antenna compensates for signal loss incurred mainly by the
connecting cable. Similarly, a low noise amplifier is attached to the receiving
antenna via a low loss ceramic filter to boost the signal sent to the telephone.
The ceramic filter has a bandwidth of 25 MHz centred on the Iridium band
designed to attenuate any out of band interference that may arise, for
example from nearby Inmarsat uplinks.
Using manufacturing techniques proven for a range of extremely rugged
GPS/DGP active antenna, the base is milled from aluminium and hard
anodised, giving an attractive finish, which is mechanically resilient and
resistant to corrosion. The antenna’s mass is 0.8kg.
Introduction | Applied Satellite Technology
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.
The warranty will be invalidated if damage is caused to the antenna by the
shortening of coax downleads.
AD510-40 Power Break-In should be positioned close to the telephone basestation or handset. The coaxial down-lead is then attached to the N type
connector on the AD510-40 (figure 3 & figure 4).
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
protected against output short-circuiting by a fuse, which is resettable by
disconnecting the unit from the +18 to +36 v DC supply.

With all connections made, the telephone can then be turned on and used as
normal - it is transmitting into a load impedance equivalent to a matched
passive antenna. The gains of the antenna transmitter and receiver are factory
set to compensate for the total attenuation between the telephone and the
antenna, mainly determined by the coaxial down-lead. Consequently, the
signal output level and frequency from the antenna is equivalent to that
radiating from a passive antenna mounted directly on the handset, subject to
the antenna transmitter being a linear device. Transmitter linearity is verified
with test protocols using an HP 8591 EMC analyser that also ensure there are no
spurious out of band emissions.
