If your SWR is that high I would just adjust the antenna and you should be fine. The SWR has to be 1.5 or lower. Would you do is set the CB to channel 19 or 20 and then get to antenna and adjust collar on antenna and then press the transmit button on mic and see what meter says. If it goes higher turn collar other way.
I have the stock antenna with cobra CB and my SWR is 1.5 and the CB works fine. I wouldn't invest into another antenna but that is my opinion.
Hope this helps.
