I'm a bit confused about what you're asking.  You discuss antennas but you show pictures of a GPS receiver.  They're not the same thing.  I use a puck antenna.  They cost about $6 on ebay, and take their power from the coax.  Normally your GPS receiver supplies power to the coax, so you don't ha

Bert, Hard to predict without looking at the details. The main battle for a sine-to-square is to fight white and flicker phase noise as well as additive repetitive signals such as 50 Hz power noise creeping into the jitter. At the same time we try to get the conversion more long-term stable,
