Re: FiberOptic Satcomm



Dave,

    When ever bandwidth is available there seems to be a use for it.  Fiber
is just an easy way to run all of that data (voice, cw radio control, rotor
control, video, etc.) to the 'mast'.  I mentioned before a LAN cable could
probably used as well if the run is not too long (there is almost no limit
to the length for a fiber).  A Local Area Network 'LAN' type connection
could even be replaced with a broadband microwave link (finally a use for
those $20.00 gunplexers) to a better location for antenna installation.  The
fiber connection I envision is not expensive at all.  It would be cheaper
than multiple runs of expensive coax, and much easier to work with.

73,
Joe
