Antenna having protrusions with stepped widths

A repeater system, comprising:

• one or more amplification and filtering signal paths;
• and
• a wire antenna configured to be communicatively coupled to the one or more amplification and filtering signal paths, the wire antenna comprising:
• a center feed line that includes a top center feed line and a bottom center feed line;
• and
• a plurality of antenna elements carried by the center feed line,
• wherein a wire element in the plurality of antenna elements has a selected length and a selected width with a first end of the antenna element carried by the top center feed line and a second end of the antenna element is disposed distally from the bottom center feed line,
• wherein two or more antenna elements of the plurality of antenna elements each include a protrusion with a stepped width, over a selected length, the protrusion located proximate to the second end of the antenna element, the protrusion having the stepped width that is greater than the selected width of the antenna element.
