From experience I know that such an antenna does not always show a low SWR, and that the placement of the antenna is important (height above ground, nearby objects, etc.) in determining the SWR of an otherwise resonant antenna.<br>
<br>
Also important is the method of feeding the antenna and connecting it to the radio. I also have been saying that SWR, when measured at the transceiver, is an indication of the match between the radio and the antenna system, not [just] the antenna itself - the antenna system includes anything from the antenna jack on the back of the radio all the way up to and including the antenna itself.<br>
<br>
Another thing I say is that the matchboxes commonly called "antenna tuners" are matchboxes, not antenna tuners. They are impedance matching devices. If the radio wants a 50 ohm load, the matchbox makes sure that, whatever the actual impedance of the load (antenna system), a match to 50 ohms is obtained.<br>
<br>
I found an article that says it better than I can, and has examples: <a href="https://hamradioschool.com/good-swr-and-antenna-resonance/" rel="noreferrer" target="_blank">https://hamradioschool.com/good-swr-and-antenna-resonance/</a><br>

Thanks for reading,<br>
