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.
