Re: Helical Antenna "Spin" Determination?Scott is correct: Same sense (right hand versus left hand) for a point to point application. Note that it's not left hand or right hand polarization; it's circular polarization with either left or right hand sense.The accepted method used by most commercial antenna designers and manufacturers for determining sense (left or right hand) is to view the antenna from the rear and note the direction of the antenna element as it spirals or launches the wave away from your eye: Clockwise = right hand sense, counter-clockwise = left hand sense. The PWS antennas are easy to determine owing to the clear plexiglass. The Sennheisers in general ship right hand but I believe left hand can be ordered.Justice - The ARRL Antenna Handbook is an excellent reference aimed at those with less than a PhD.
