Hi Markus, I am using two identical DC receivers sharing one LO. One feeds L and the other R to SL respectively. With this settings, I can compare two different antennas at the same time. I am using two mini-whips (of PA0RDT design) with the following setup. http://icas.to/argo/dcf39/side-view.jpg http://icas.to/argo/dcf39/top-view.jpg The lower mini-whip (No.1) seems to be 5db or so better than the higher mini-whip (No.2).
