An open wire fed dipole would give pretty good performance. But, feeding
such an antenna with RG-8 and living with a high VSWR (maybe up to 10:1)
shouldn't be discarded.
A dipole of about 18 feet would cover 24 and 28 MHz with about 5:1
VSWR....not bad.

Yes. My Yaesu ATU gives up at 5:1, so I have been using a more robust
homebrew tuner.
A VSWR of up to say 10:1 (perhaps 15:1) shouldn't be a deal killer, if you
can match the coax and are willing to accept 2-3 dB of loss. This opens up
a lot of antenna possibilities that might be otherwise discarded.
