Hello, I don't have this product, but from my experimets:
1. Take in account losses from cable - more cable less pwr voltage 2. I repair one of my gps antenas. Inside is 2 stage mmic preamp with low-drop regulator with coil. 3. My friend in his antena ( the same model ) don't have any low-drop pwr, but simple diode with resistor and coil. We cooced our anetnas by sily mistake - no more unlabeled BNC connectors in shack :) ( mistake - trasmit 20 W RF @ 70 cm band into GPS antena ) Vy! 73 de Artur SP5QA 2008/5/28 Christian Vogel <[EMAIL PROTECTED]>: > Hi, > > I acquired a GPS antenna for use with a Trimble Thunderbolt (which > provides +5V antenna supply voltage) on ebay.de this week (seller > "gps-laden").
