When you say for travelling - if you are travelling in your car, then a fishing pole supported Inverted-V or end-fed is probably the safest option (and not a compromise, except that the end-fed needs wither an UNUN or ATU).
If you’re taking travelling in a plane, then you need something that collapses down - yes there are small fishing poles like the 5 & 6m €30-35 ones from Lambdahalbe
but if you also want to be able to set up and take down quickly in a restricted space, then a HF vertical on a modified photo tripod (SO239 socket plus coax and counterpoise/radial wires added) is what I use. My antenna of choice for this set-up is the Komunica HF-Pro2 but it does have quite a long whip on it, a shorter and not as effective similar (tune the bottom) vertical antenna is the Diamond RHM-8B but it also costs twice as much as the Komunica and doesn’t perform half as well.
These are both 80-10m solutions. Komunica also do a wide band (no tuning required) Bazoka Pro - works well on 40m but not so well on other bands - the HF PRO-2 is a far better option.
