Hi Chris, Even if this is the datasheet of a later version, it gives an overall picture of what you ask about.
http://trl.trimble.com/docushare/dsweb/Get/Document-383329/022542-010B_Thunderbolt-E_DS_0807.pdf The Tbolt perform (even) better with stable temperature surroundings. 3m of antenna cable is no problem. Antenna position is more important than the exact type of antenna. I'd rather have a decent antenna at a very good site, than a very good antenna at a slightly worse antenna site. My Tbolt with internal 24VDC PSU draws 200mA at 24V -> ca 5W. This is in steady state at about 22C. -- Björn > > > 10/06/2012 22:26 > > My Thunderbolt, PSU and antenna should arrive this week.
