Quadrifilar Helix Antenna 2 4GHz

In this video I give you my version of the Quadrifilar helical Antenna for 2.4GHz. The antenna is capable of much higher gain than a cloverleaf antenna, so should give much more range.

    The semi rigid coax is RG402, which you can find for a few dollars on eBay. I've found it's cost effective to buy 50cm cables with RP-SMA Male connectors each end, then cut the cable in half for two antennas. The outer braid is conductive.
