Pete,
I started the thread because I'm finally getting my garage/shop completed
and populated. I settled on a couple of Extron ADA3 RGB video distribution
amps (I found two units Ebay for a grand total of $40 including shipping).
I've hooked them between a TBolt GPS and my HP 5328A and HP 5334A counters,
Montronics (Fluke) 103A Freq Comparator, and some other misc stuff.
Monitoring the signal level and quality with a scope, I can't tell the
difference between the outputs and the input. I don't have a spectrum
analyzer (yet) to see the real picture, but it's working pretty well for me.
The noise is below my ability to measure for now, but I hope to be geared up
for that in the summertime.
You can read more info on the ADA3 at Didier's site at

for using an Extron DA.
