Helical Antenna Design - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

Below are the old forum threads, including responses to the original posts.

Hello - I'm an audio, not an RF guy,
and I'm having difficulty Googleing concise info regarding the basic design/theory of operation of helical antennas. I've found pix and plans for axial/endfire helicals, but not what has been described as "normal"/spherical/hemispherical/omni designs - the one with the radiation pattern that can best be described as torroidal or omnidirectional, rather than hypercardioidal. Any leads appreciated!

I have used a company in the UK, called European Antennas, for these type of antennas. They have a wide range of products for all of the applications, and its far easier than building them yourself. There web-site is www.european-antennas.co.uk
