HAM RADIO: QO-100 Ham Radio Satellite: Ice Cone Feed versus DX Patrol Helix

Following on from a comment made on my previous video from Paulo, ‪@CT1ETE_Paulo‬ I have made a follow up video to compare the performance between the Ice Cone Feed and the DX Patrol helix antennas. Although this is an unscientific approach to comparing their relative performance, it clearly shows that one provides significantly more gain than the other! Using exactly the same setup for both antennas, I used the very useful online SDR from DB0HAL, which provides a handy way of seeing the dB peak of signals on the QO-100 transponder. http://db0hal.dyndns.org/nb.html For more information about the featured antennas: DX Patrol Helix Antenna: https://dxpatrol.pt/produto/helix-ant...
