Let it cover the surrounding signal as evenly as possible, so that the signal can be maximized. I could have sworn that I've answered this before, but I can't find the question to merge this with. Bei der Montage einer Dachantenne gilt es zu beachten, dass diese maximal 1,5 Meter von der Außenwand entfernt und mehr als 2 Meter unterhalb der Dachkante anzubringen ist. Joined Nov 17, 2017 Messages 570 Reaction score 208 Location Australia & Europe. The problem was that in trying to figure out the best direction to point the antenna I realized that there had to be an easy way to get the optimal direction for the antenna to face. In this paper, genetic algorithm (GA) is used to find the optimal antenna positions on a mobile device. Outline 1 Electrically Small Antennas 2 Fundamental Bounds 3 Synthesis: Determination of Feeder’s Position 4 Synthesis: Reduction of Degrees of Freedom 5 Synthesis: Results 6 Concluding Remarks This talk concerns: I electric currents in vacuum, I time-harmonic quantities, i.e., A(r;t) = RefA(r)exp(j!t)g. Capek, M. and Jelinek, L. Optimal Currents and Optimal Antennas 2 / 23 Some routers have no antenna at all, but some have up to eight. DAB Zimmerantennen haben oftmals in Fensternähe den besten Empfang. Je nachdem, ob die Antenne bereits optimal justiert ist, lassen sich dann im besten Fall direkt nach dem Sendersuchlauf alle Astra-Sender empfangen. jedes TV -Gerät separat mit … Now problems designing effective communication antennas can be accomplished faster and more efficiently using this technology. TV Antenna Positioning Consideration #2 - Antenna Direction. The optimal relay antenna locations are searched in each area respectively. That's when I came across AntennaPoint.com.
