So easily a 20 dB shortfall. I will look out for a similar antenna. Thanks

The ET6000 used Trimble Bullet antennae when I was selling them in the UK. I seem to remember about 35db of gain in that antenna.

I attribute a lot of this to the long 8 ft RG174 style coax pigtail. I have to wonder if the gain of the preamp as published actually includes the inherent cable loss, and even if so the preamp must be screaming in gain to make up for the loss. I intend to get a proper antenna. Here is a comparison of specs of these type antennas: http://gpsinformation.net/main/gpsantrev1.htm -- Joe Leikhim Leikhim and Associates Communications Consultants Oviedo, Florida www.Leikhim.com jleik...@leikhim.com 407-982-0446 WWW.LEIKHIM.COM _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. ----- No virus found in this message.
