Robert, My pleasure Sir!
The problem here is that the antenna may not work with +5v, and may actually need +12V. However, I have successfully done this with an Odetics receiver in the past, but the GPS engine was not a Trimble, and I don't actually know who made the antennae, but I do remember that they had both 12V and 5V versions. Worth a try though. For the record guys, I have worked directly for Systron-Donner, Austron, Odetics/Zyfer and have represented TrueTime, Datum, Meinberg, and KSI, so have some useful experience (plus a load of old manuals!!)

Any help will be appreciated. Maybe I can disconnect the 12 V & put 5 V on the antenna (internally), will try and trace the traces.

However I do know that Datum used Trimble engines in their GPS products which did not down convert and some of the earlier models did have +12V feeds for the LNA inside the antenna rather than the later and more common +5V types. Will check and let you know. Rob Kimberley -----Original Message----- From: Robert E.

Any info would be helpful, I note that it has 12 VDC on the antenna connector so I am curious if its for a preamplified antenna or an antenna/dowmconverter. I am more then happy to pay for it.

Not sure if I have this particular one, but will check and let you know.

Unfortunately I haven't the antenna that really is a special converter. I am looking for the service manual copy . Symmetricom say it haven't. I remember my Austron is only 10 years old. Someone in the word can help me? Thanks to all in advance Luciano P. S.
