Helical antennae - opinions? |

Hi all,
A mate of mine is working at a place that was considering putting in a $10,000 per month leased line to a site 2km away, but he managed to talk them into letting him trial a wireless P2P link using a Bullet and a mesh antenna - at a total cost of about $600 per side plus regular maintenance (a damn sight cheaper than $10,000 ongoing).
This reignited my interest in P2P wireless links, and had a look into it. I googled for homebrew antenna recipes and found one for a helical antenna. With about $30 in parts, one could build an antenna capable of a 18dBi boost (though probably more like 14dBi since the algorithm used tends to overestimate the signal boost) on the 5.8GHz band. With a Bullet M5HP, this comes down to about $280 per side, but if I order them from Microcom, that sinks lower to about $220, including PoE and a 6GHz surge supressor.
My question is: would the helical be the way to go, or are there better antenna designs out there?
Regards
