Most antennas for the VHF marine band are manufactured to be mounted on vessels. If you wish to become a mobile radio facility you will need a different kind of antenna
depending on where and how you want to mount it.
On my pickup, I have an
NMO mount in the roof and 1/4 wave antenna cut to 18 in. This allows my truck to
fit in my garage. You can also use a Larsen Magnetic mount NMOMM ($31.95) if
you don't want to drill a hole.
On my car, I have a NMO trunk lid
lip mount with a Larsen NMO150BCO coil ($25.25) and a Larsen W490B 5/8 wave whip
($13.50) cut to 43-7/8 in. for the marine band.
These can beI purchased from Ham Radio
