Always check SWR for yourself, do nottrust the blurb ( good SWR doesn't mean the antenna is working well, just that it is presenting a correct 50 ohm load. A 50 ohm resistor SWR's 1:1 but it doesnt transmit well. It has been known for antenna manufacturers to stick big resistors into their antennas to ensure excellent SWR figures!

Some ofthe pre tuned antennas may be difficult to re-tune as they are sesigned to be left alone.

A seeing SWR the whole time is a good odea, but it can rob power and sometimes causes TV interference. A lot of good quality modern rigs have internal SWR meters taht can be left engaged permanently. This is good practice as yo are always monitoring the condition of your whole antenna system ( eg plugs coax and antenna)


As always not a definitive yes no answer but hopefully you can make your own choices based upon it.
