I did a goofy little experiment with my CB whip vs. a 10M double bazooka dipole antenna to see if I could make out any difference between them. Both antennas had rather poor SWR for 10M. The CB whip is resonant at 12M**, and between 5 and 10 across 10M. The vertically hung double bazooka had an SWR between 2 and 3 across 10M. I conducted this while parallel parked in Boston. The antennas were in close physical proximity to each other. I tested then sequentially using a portable wspr unit transmitting 200mW. I tested each antenna within a few minutes of each other. I figured that the feedline loss would take care of any reflection in power back to the transceiver. It seems my wspr unit still works. These are the results, with 3 unique spots each. So, obviously there is not much I can conclude from this experiment. Except possibly why I have such trouble with my cb radios (given the lack of resonance on 11M). But it was fun to do. I did not have many spots. Looking at the world wspr data, it did not seem like anyone did at that particular time I transmitted. I wonder if FT8 would have shown more results. It was fun to try. Something I can do right in the middle of the city. Gets me using a lot of my ham radio gear. Gets my mind thinking (why did I get such similar results between the two antennas?) And helps me learn and explore the wonderful hobby of amateur radio. Just thought someone out there would enjoy this ugly little experiment. Mindy **EDIT: oops, I take it back. I did not realize the rigexpert has a blue band for CB. SWR actually looks good there!!
