Well, swr depends on a lot of things including the environment.? ?You can trim the wire and adjust the turns to get it resonate on all 3 bands.? Having said that,? you will get slightly different results depending on the location.? ?I always use a tuner.
I have a suggestion.? ?Why don't you buy one of the Chinese verticals with base and stake for less than $30.? Add the coil for 40 and 30 and you are good to go.
