[QUOTE="peterwo2e, post: 100990, member: 18906"] this is an old post but here is my 2 cents, any antenna that is vertical (standing up) is omnidirectional and vertically polarized if you take this same antenna and put it horizontal (flat down) it will still be omnidirectional but horizontally polarized, punting another antenna or metal element close to it would make it directional as it will disturb the signal pattern. example the TV roof antennas are directional and they are horizontally polarized. putting the spark 2 antennas outside the craft and as far apart as possible is a great idea. and most likely would work a lot better if you can put the antennas Horizontal (remember the RC antennas also has to be place horizontally) the reason! is that horizontal would eliminate most interference like microwaves, transformers, motors, etc, etc. when they made the spark a lot when into packaging all that technology into a small area. so performance had to be compromised at some point. just my 2 cents.
