Antennas led astray

... of a three dimensional vector. The two dimensional term Art: I take the thrust of your previous text to say, "We have lost focus of the antenna as a technical device. Some now think of it as a "magical device" and some as a "work of art." I can see some truth in all of that. Plus, I will go further, if anyone thinks we have discovered ALL there is to know about antennas, they are simply wrong ... Basically, I only have use for three types of antennas. Two of these are for terrestrial use only and one is for non-earth use ("talking" to satellites, NOT aliens.) Of the two for terrestrial use, one is omni directional the other VERY directional. Now omni is quite easy, most dipoles or monopoles can be placed to work with varying success. So that leaves the "beam" or directional antenna. Now, the best directional antenna I have EVER found is the parabolic dish--there just ain't any better! However, for HF (indeed vhf/uhf are VERY difficult to construct) these are out of the question for most of us. So, the question becomes, "How can we mimic the performance of the dish with practical materials. Now, that is what we are all looking for, isn't it? Warmest regards, JS |
