When I moved here, the first antenna I put up was a vertical doublet, reasonant again somewhere between 30 & 40m. For convenience it was fed with coax (coiled to form a choke at the feed point) & force fed by a tuner in the shack. It obviously took a hit in line loss on 30, but usually was better than the current shunt-fed roof tower on 40.
I just don't have a feel for what a tuner might be able to handle & would prefer to know there's a reasonable chance of making the loop work before I put one up.
