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.

I don't know if it will help but for the ground plane part of the
antenna, you could use a pizza pan (16 inches should do it) and find
some way to mount it on the roof of either the metal or the fiberglass
roof.


Thanks in advance.

you are welcome, but I thing I only gave you something to think and
build on.

Cute, but I don't think I would want to 'meet' one of those
locomotives in your car ;(

Good luck
