A helix is a broadband antenna and used with a ground plane. This antenna is used in satellite communication devices such as telephones radio and global positioning systems (GPS).
|Create helix or conical helix antenna on ground plane|
|Create helical dipole antenna|
|Creates bifilar or quadrafilar helix or conical helix antenna on circular ground plane|
|Create balanced bifilar or quadrafilar dipole helix antenna without circular ground plane|
