This detail might help you tune your antenna to frequency a little quicker / easier than otherwise : https://www.vk4adc.com/web/index.php/hf-...na-lengths
When you don't use a balun then it becomes a little trickier to tune a(/each) dipole as the feedline causes interaction with the polar pattern due to interaction with the dipole half that the braid-side connects to. The inclusion of a balun largely removes that interaction.
A 'ray dipole' consists of multiple frequency dipoles connected to a common feed point BUT the dipole sections must be spaced apart physically as they expand from the feed point to make them easily tune-able.
