Don't know if the CB Shops still sell them but we/they used to call them "T-Bars". Very popular with the 2 or 3 is better than one crowd. Mount them high enough on the vehicle and you can take-out all the fluorescent lights in your favorite Gas Station with a simple drive-through. Just playing devils advocate here... the above setup is kind of unwieldy for most people and bumper or ball mounts on a newer car is sometimes problematic. You don't really need two different antennas, you can "probably" fairly easily make or find some type of a dual band antenna with the obvious sacrifice of a bit of band-width. But I'd like to talk on the Amateur Bands and I sometimes need to talk in both the 33 MHz and 43 MHz ranges. One reason I have a few other options in place that clearly trade performance for acceptable SWR. Once again, "something small is better than nothing at all"... cheers, s.
