Hi Bill, I have no knowledge of the interfaces and functions. I am with you, the problem seem to be with the device from Lucent. I am running successful the original Trimble Tbolt I got from Tom,TvB, (thanks again Tom!) now since long years. I am happy so far with it, a good base as 10 MHz

Andy, Good point, up to a point. But even if the antenna's amplifier itself has a good return loss, cheap cables like RG-174 are pure garbage and could be doing just about anything along their length. And if the bottom end connector is put on by a person without training and the correct

[time-nuts] Antenna return loss

2021-07-29 Thread Andy Talbot
Much talk about source return loss and splitters. All active GPS antennas I've met have masses of gain at the top end, 40dB or more. Most of the small puck ones come with several metres of RG174 thin coax. This is so lossy at 1.6GHz that that several metres may have perhaps 10 - 15dB loss. So

Hi there, thank you for all the information. I'm using a bullet antenna (don't remember the maker), on top of my office. Cable has 50ohm impedance (ultraflex 7) and average quality N connectors. Patch from splitter to receiver is 50ohm as well, but still using RG58, will upgrade it asap.
