Default Antenna suggestions for Vertex FTL-2011 mounted on Metal andfiberglass railroad equipment.

I'm new to this and need your help in selecting which antennas to use
on my railroad motorcars.

The radio will be moved between two pieces of equipment. One cab has
a flat metal roof and the other has a fiberglass cab. I would like an
antenna that I can unscrew from the cab when traveling the equipment
down the road on a trailer. The radio will be using the NARCOA
licensed frequency of 151.625 MHz. I understand that this frequency is
in what is known as the VHF-High Land Mobile Radio (LMR) Service band,
and uses a modulation known as narrow band (5 kHz deviation) FM. I
will be using a Vertex FLT 2011 40 Watt radio.

Based on the little I know about this, I understand a special antenna
will be needed for the fiberglass cab since there is no ground plane.
Both antenna will be mounted directly to the roof through a hole. The
radio will be mount within 2 feet of where this hole will be drilled
so I only need a short wire to connect from the antenna to the back of
the radio.

If you can offer me suggestions as to which antennas to use, I would
be most appreciative. Please excuse me if I misused some of the
language of the hobby.

Thanks in advance.
