Well, "necessary" and "present" are two different things  Most of the little bitty corona balls that are on cb antennas like this one are so small that they're almost useless and won't affect the SWR much, if any. A corona ball can be absolutely necessary on lower bands (75 meter, for example) if you're running any kind of power at all to prevent arcing to nearby objects. (Ask my wife about what she saw one night while I was mobile and parked underneath the tree out front!)
At 10/11 meters, you're not going to have that problem without pretty large levels of power, but what the corona ball can do for you is reduce static build-up while driving, which you would hear in your reception. I suspect that's the biggest impact you will have with the little corona ball on the Wilson 1000. |
