Modems
Iron Link supports many varieties of modems. The key
settings that your modem needs to support are: QPSK,
VITERBI, code rate 7/8 and ¾, with these parameters
we will be able to support your modem type to activate
an SCPC satellite link. We highly recommend newer
modems with the TURBO function as the increase in ease
of use and performance is substantial, which can in turn,
translate to operational expense reductions. Iron
Link sells a variety of modems and we test each before
shipment to you. In the near future Iron Link will
also support DVB(s2) operations – check back to
see list of compatible equipment coming soon.

Transceivers
The remote site transceiver may be a 70mhz or 140mhz
type unit – as long as the transceiver is C-band
(check for KU compatibility) we will be able to bring
up your services. The key option or specification
to look for is weather the transceiver is dual or single
synthesizer. Though dual synthesizer is always
preferable (that you are able to change tx and rx frequencies
independently) we can support single synthesizer (tx
frequency automatically sets rx frequency at a fixed
offset) on certain satellites. Iron Link sells
a variety of transceivers, each is tested here before
being shipped to you.

BUC
L-band remote terminals are becoming very popular and
are now very reliable as well. Though the L-band
modem is usually more expensive, the whole package for
the remote earth station is much less expensive in the
L-band option. Keep in mind, the package is called
L-band but the actual satellite frequencies it works
on is either C-band or KU-band – most L-band modems
will work with either C-band or KU-band BUCs. Watch
for power requirements and L.O. setting requirements – make
sure your modem can support the BUC you are planning
on using. Iron Link sells a variety of BUCs, each
is tested here before being shipped to you.

Antennas
Iron Link teleport can support antenna sizes as small
as 1.2M in C-band, though if the remote antenna is smaller
then 2.4M the service becomes more expensive as a smaller
antenna forces us to use more power on the satellite,
and we do get charged for that usage. Bigger is
always better as far as price and performance – try
to use at least a 2.4M antenna for C-band applications
and at least a 1.8M for KU-band applications – but
remember that we CAN work with smaller size antennas
at an additional cost. Key options to watch for
is weather the feed is LINEAR or CIRCULAR, Iron Link
operates on satellites that support both types, but pricing
varies depending on which one your antenna has. The
other key option is weather then antenna is prime focus
or offset, for most remote site operations, we suggest
the offset antennas. Iron Link sells a variety
of antennas.
