Hi Dick, See page 27 of this document (as numbered at the bottom of the page, or PDF page 29): http://trl.trimble.com/docushare/dsweb/Get/Document-388613/ThunderboltE_UG_1B.pdf
The Trimble Bullet antenna for the TBolt has ">28dB gain" and they recommend RG-59 coax. Brooke's page ( http://www.prc68.com/I/ThunderBolt.shtml#Ant ) mentions the TBolt is happy with an antenna gain between 18 and 35dB. He also mentions to watch out for the voltage to the antenna. A lot of newer antennas run on 3.3 volts instead of the 5V being injected up the line by the Thunderbolt. I'm having a problem with Symmetricom clocks at work where they switched to injecting 12 volts up the line (previously models were 5 volts) so I had to get up on the roof and swap antennas. -Bob On Mon, Jun 13, 2011 at 1:56 AM, Dick Moore <rich...@hughes.net> wrote: > Once again, thanks to all.
