Quick mount detachable antenna and mounting

A quick-mount ADS-B system, comprising:

• a base removably carried by a vehicle, wherein the base has a first longitudinal dimension, a forward end, and a rear end, wherein the first longitudinal dimension is aligned with an expected direction of movement of the vehicle, and wherein the forward end is rounded to reduce aerodynamic drag on the base, the base including;
• a beam carried by said base, wherein the beam has an elongate lateral opening and a second longitudinal dimension, the second longitudinal dimension aligned with the first longitudinal dimension;
• a global positioning system (GPS) antenna carried near a first end of said beam;
• a monopole antenna carried near a second end of said beam;
• and
• an ADS-B transceiver electrically coupled to said monopole antenna, wherein
• the elongate lateral opening of the beam exposes a connector that couples to the monopole antenna to electrically couple at least one of the GPS antenna and the monopole antenna to the ADS-B transceiver after the base is attached to the vehicle,
• a GPS receiver electrically coupled to said GPS antenna, said GPS receiver operably coupled with said ADS-B transceiver, and
• the GPS antenna is separated from the monopole antenna by a longitudinal distance to minimize an electromagnetic coupling between the GPS antenna and the monopole antenna.

A method for enhancing safety, comprising:

• attaching a cradle to a top of a vehicle, the cradle having a rounded forward end to reduce aerodynamic drag;
• removably receiving a base, wherein the base has a first longitudinal dimension, wherein the first longitudinal dimension is aligned with an expected direction of movement of the base, wherein a beam is carried by the base, wherein the beam has a second longitudinal dimension greater than the first longitudinal dimension, wherein the second longitudinal dimension is aligned with the first longitudinal dimension, and wherein the beam has a monopole antenna and a global positioning system (GPS) antenna to the cradle attached to the top of the vehicle, the GPS antenna being separated from the monopole antenna by a longitudinal distance to minimize an electromagnetic coupling between the GPS antenna and the monopole antenna;
• electrically coupling said GPS antenna to a GPS receiver;
• electrically coupling said monopole antenna to an ADS-B transceiver;
• and
• operating said vehicle in a vicinity of an airport while receiving location information by said GPS receiver and transmitting position information by said ADS-B transceiver.
