You should investigate the usage of a mobile antenna, such as the GPSx

GPSx Survivor - Model GPSDVHF
This very durable antenna features a 26dB gain active ceramic patch GPS
receive antenna with a durable black chrome plated, shock spring protected
VHF ¼ wave antenna in one complete package.
The real advantage of this antenna is its mechanical integrity. This dual
band antenna is constructed with a fully potted heavy wall resin housing, a
one-piece solid brass mounting stud, a large diameter tapered shock spring
and a tunable 0.100" diameter 17-7ph stainless steel radiator for VHF. All
of this makes it perfect for heavy equipment asset tracking and monitoring.

It comes complete with 14 feet of RG174 terminated with an SMB connector for
GPS and 14 feet RG58A/U terminated with N connector. It is mounted through a
5/8" diameter mounting hole and secured with an included heavy stainless
steel jam nut.

Sounds like a good solution.

However, I would not call that a dual band antenna, but two different
antennas mounted in the same package.

How is the active GPS antenna powered?

Happy trails,
