Very slightly directional, but not worth 'aiming'. Just go for the most convenient mounting.

I found some build instructions here

http://www.iw5edi.com/ham-radio/?halo-a ... r-70mhz,83

We always used to refer to circular ones as 'halos' and square ones as 'squalos', but these days they're all called 'halos'.

You can stack them vertically to get omni-directional (or very nearly) gain, but you need to make a phasing line.

You do realise a halo is horizontally polarised?

that halo design is easy to build. I had my design in my "Antenna Workshop" Practical Wireless some years ago. All designs are the same . Just the mechanicals might be different. 73 David
