i am considering building two movable (concrete base with wheels) non metallic poles with hooks every ten centimeters or so, in order to test wire dipoles of various sizes at various heights with an antenna analyzer, far from obstacles (let's say in a field).
Do you think it's better to use non conductive masts to avoid parasitic influence on the measurement or is it overkill? Is there anything else on antenna metrology I should know for this project?
