As has been mentioned, several outfits make desquised antennas, but are
expensive. Also, the BIG problem, in car radio antennas isn't the antenna,
but the FEEDLINE (coax) for it- center conductor is about the diameter of
#26- #30 wire! And to compuund it, todays vehicles are so stuffed under
the dash, it is hard to get to the coax/motorola fitting. But, if (and
have done this in the past), can get to it, and replace it with rg-58-u,
little detrement was observed to am/fm reception, and then the antenna, if
sized with a swr meter, for 1/4 or 3/4 wavelength , works well . also, think
(at least for 2 meters, some outfits still make antenna tuners for
vehicles)! or, build your own tuner/duplexer (about $20 in parts, max)
(course, like the one about leaveing the XYL/kids in the trunk, especially
if it soundproofed)! Jim NN7K

I mount the rig under the seat, the control head on the console, the
dealer ran the power cable as part of the deal on purchasing the car,
and the antenna is a Diamond mag mount with a 5 foot plus collinear in
the middle of the roof.

My wife has one too, but as she puts her car in a regular size garage,
the antenna is only about 14 inches tall.

Generally on the modern cars there are a number of places where you
can run the power cables through a boot that houses an existing cable.
The mag mount I snake out a door, or window. On my SUV I use the door
behind the driver as it's almost never opened. The coax is snaked
into and under the weather seal about half way down and then follows
under the seal up to the top to the antenna.

Most cables fail within a year, but his one is over 7 years old.
Rig is a TM-D700.

I'm wanting to keep peace within the family.. NO! Extra antennas on the
vehicle..
I want to install a dual band 2m/440 mobile using the AM/FM antenna that
is
on the vehicle.. It will be mostly used for receive, BUT....
Other than a duplexer and tuner (s) What is needed to STOP the RF from
damaging the AM/FM radio in case I want to transmit?...
Any help on this??
