The triangular loop antenna for sailboats is designed to operate in a ground-
less environment and still provide high performance. This type of installation
will require only one insulator point on the bottom backstay and an electrical
connection on top of the mast and stay. The grounded side of the coupler is
connected to the bottom of the mast. Although not our best recommendation,
this antenna will provide a workable solution in some installations.
