A turnstile is a horizontally polarized antenna. Big downer is that from a
polar radiation POV, from the sides, it's got a minus figure. Like -2db or something. Okay, flipp the turnstile so you have one dipole vertical. Not a turnstle anymore, and the element configuration will respond favourably to both vertical and horizontal radiation. But: 1) Do you have to wire up the "flipped turnstle" in a different way in order, at the same time, (without any switching) to take advantage of: a) mixed polarized waves? b) vertical or horizontal waves? 2) If you put up a "flipped turstile" and you wire it up to handle mixed, vertical or horizontal waves, what is the polar radiation patter in the horizontal plane (ie from the sides) ? Still a minus? Amhoping that a "flipped turnstile" properly wired would perform with mixed, vertical or horizontal waves coming from the sides. And hoping better than a turnstile. TIA. |
