The ‘problem’ with long antennas relative to the frequency that get deployed randomly is the pattern is not that predictable. It often looks like a hedghog’s backside with spikey lobes pointing anywhere and everywhere. Sure it will work and if a lobe happens to point in the right direction then result! But it can be hit and miss.
Mine is exceptionally docile. It always has a nice match no matter what ground it is above. It seems to work when there is propagation. My setup needs a tweak to make deployment easier but it fits on a 5m mast so it’s not massively unwieldy. The full info for mine is on here (Delta loop antenna on higher HF bands - #30 by MM0FMF), the setup should be omni directional and vertically polarised. You do need a length of 75ohm cable to make the match section.
