no counterpoise
i have a 5/8 vhf antenna (with coil at bottom) with nmo mount. if i cut the
wip down to 1/2 wave will it work without a ground plane? i want to put it on my fiberglass boat. i see marine antennas that are 1/2 wave with a coil at the bottom. i would like to adapt a antenna i allready have. |

joe bob, You'd still have a problem because then the coil at the bottom would be the wrong size/value for a 1/2 wave antenna. 'Doc |

Add a small ground plane. Aluminum foil on a suitable support, piece of
plywood etc., would work fine.

Why use a ground plane. If you re on the boat in salt water use the ocean
