Have to agree with JJD. Had a local with a 3 element beat up at 85ft and could talk to whoever he liked around locally out to nearly 100 miles. Just swing it around to where you want it.

Smith charts for an antenna will also give you more of an understanding of how an antenna will perform

Back in the end of the 70's , into the early 80's, A long john 5 element beam mounted horizontal with a big stick in the middle. Didn't matter, you could be heard on either polarization even when only feeding one. The take off angle from the big stick enabled skip on the short hop of 600 miles. A station 40 miles away had a 5 by 5 reading around sunset and sunrise with 25 PEP but took 100 PEP to get reliable daytime over that distance.
It is my understanding that you can do it, it's just not efficient. Square peg round hole.
Atmospheric conditions could be at play also.

if you're radiating enough signal from your coax for it to act as a vertical antenna you've got some really shitty coax and it needs to be replaced before you damage your transmitter/amp . the shield on coax is designed to keep the signal inside till it reaches the radiator . common mode currents can travel to the shield side of coax and radiate and typically cause problems with other nearby electronics but they don't travel far enough with enough energy to outperform a horizontal dipole or beam .

Conditions can change the polarization of a transmitted signal. Skip can switch the polarization. A slopped, long wire antenna is best but can become somewhat directional.
