Not in this case. The TA-33 will absolutely benefit from use of a choke
balun at the feedpoint. It is idiotic for any antenna "engineer" to NOT use
a balun when feeding a balanced load with an unbalanced line, unless the
intention is to excite the boom, tower, feedline and everything else as
part of the antenna.
By all means, either use ferrite beads or a coiled up length of coax as a
**choke balun**. It will improve antenna performance by divorcing the
balanced element from the unbalanced feedline.
