I would like to test two GPS antenna with one same GPS receiver. It is
really inconvenient to switch the antenna back and forth manually, since
my computer is not close to the test lab, and I can only run my software
in my computer, and the GPS receiver at the lab. I can't bring my
computer to the lab, or install my software to a test computer at the lab.
Is there any RF GPS Antenna awitch available, that I can switch the
antenna remotely from my computer? I wish there is a product that can
support 2 or more GPS inputs (from antenna), and one GPS output (to GPS
receiver), and a USB or Ethernet connection (to a test computer at lab)
to receive the commands from a remote computer.
Thanks.

I haven't been able to find out a command-able RF switch yet. However, I

You would require an RF power divider, such as a Wilkinson splitter.
Very rude (but it works) splitter on my site at:
