That antenna was built to be usable in that frequency range. That just means it can be tuned to work in that range. You still have to do the tuning/adjusting.

The 1.5% range isn't for a 1.5:1 all through that range. It just says that the SWR will be under an unusable value. What's that high SWR value? Typically something on the order of 2-3 to one. Sorry, it isn't going to be 1.5:1 all through that range, that just isn't being realistic.

I think that the 'convenience' of having a short-whip antenna proves to be an 'inconvenience' when it's time to do its job - transmitting and receiving. But then again - how much can you expect from a cheap/short antenna?

Yeah, the NMO mount is great but unnecessary for CB. If it was my vehicle, I would change out the mount and put a Wilson 1000 or 5000 up there that has a 5 1/2 ft whip. They have a usable bandwidth of .8 MHz. Or a Sirio 5000 Performer with a 6 1/2 ft long whip - which has a usable 1.1 MHz bandwidth. (BTW - all bandwidth measurements were made using an MFJ-259B antenna analyzer on actual antennas mentioned)
