Relative directional recep-tivity of modified longitudinal array of two Houlton antennas. (Short) directional diagram caused by the longitudinal array. A map of thisarray is shown in Fig. 12. The circuits for combining four antennas of an array of the type TRANSATLANTIC RADIO TELEPHONY 339 quite evidently combines the narrowing of the directional diagramdue to the lateral array and the reduction of the back end area of the. 0 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160 170 180 360 350 340 330 320 310 300 290 280 270 260 250 240 230 220 210 200 190 180 ANGLES OF INCIDENCE (e) - DEGREES Fig. 13—Wave-antenna array directional characteristic.
