Serious Question about my antenna

im building a collinear coaxial antenna at home and i dont get any 1090 mhz signal, its a 8 elements antenna (i did all the calculations and the length of each elements is 116mm ), but my question is... Im using 8 elements and in the end of the 8th element its the feeder cable (7elements and then the feeder) should i add one more element? so theres 8 elements + the feeder cable? is that right? I mean, once i add the feeder cable to the 8th element, my multimeter read theres continuity... should NO or Should be continuity at the end?

Thanks
