Because the RF between this antenna/converter and the GPS75 is a lower
intermediate frequency, not the 2400 Mhz microwaves from the birds, any
coaxial extension cord with a BNC male on one end and BNC female connector
on the other works great to move the antenna away from the GPS75, Same
old, cheap RG-58 from RatShack works fine.

Well close but no cigar on the above.....GPS runs at 1.6Ghz, and I have
never seen a Garmin GPS that downconverts in the remote antenna. Mostly
what Garmin does is have a Powered LNA and Patch Antenna in their remote
antennas that feed the Reveiver at Frequency. My Garmin GPS3 and GPS3+
both are this way, and all the earlier Garmins with external antenna
capability are the same as they can use the same remote antennas.
