Why? You going to build this? Well, it can't be built. The ICE 180 Matching Transformer 'acts' as the Collection Point for each of the Signals coming from the Four 'individual' Wire Antenna Elements. Do you understand that these signals are vectors with magnitude and phase not just magnitude? That is a rhetorical question don't answer it. In this instance the Four Taps on the Antenna Side of the ICE 180 Matching Transformer 'act' as a Summing Network. The Output of which is fed {transferred} to the Coax Cable Side of the ICE 180 Matching Transformer. Each of the Wire Antenna Elements is 'separated' in Space. 15.1 Feet & 19.7 Feet & 24.5 Feet & 38.5 Feet Deltas : 4.6 Feet & 4.8 Feet & 14 Feet = 23.4 Feet Each of the Wire Antenna Elements is a 'different' Length -wrt- Wave Length; and therefore 'unique' to itself. 39.6 Feet & 51.5 Feet & 63 Feet & 97.7 Feet Collectively All of the Wire Antenna Elements add-up-to More Wire In-the-Air and a Greater Signal Capture Area. Not necessarily. More Wire In-the-Air : 39.6 Feet + 51.5 Feet + 63 Feet + 97.7 Feet = 251.8 Feet Long Greater Signal Capture Area : 300 Tap "L" by itself : 15.1 x 24.5 / 2 = 185 Sq. Ft. 450 Tap "L" by itself : 19.7 x 31.8 / 2 = 313 Sq. Ft. 600 Tap "L" by itself : 24.5 x 38.5 / 2 = 472 Sq. Ft. 800 Tap "L" by itself : 38.5 x 59.2 / 2 = 1140 Sq. Ft. Collective Areas : 2110 Sq. Ft. filled with Four Wire Antenna Elements versus anyone of the single Elements. Where did this idea come from? It makes no sense. The wire impedance is determined by its diameter and height above ground. This aspect of a single wire is independent of the frequency of operation but nearly any other aspect is dependent on frequency. Summary : All of this is not 'scientific' but simply a practical approach to puting : More Wire In-the-Air by using a specific feature of the ICE 180 Matching Transfromer : The Taps. It doesn't work that way. You could add a wire to another and have less signal or more signal. yes - i know that 'in-theory' i am wrong -but- practically speaking i am . . . sort-of kind-of right - iane ~ RHF . No you are just wrong. -- Telamon Ventura, California |
