Why it matters in the field
Height, included angle, leg slope, feed-line departure, surrounding metal, and ground affect impedance and pattern. An inverted V is not identical to a flat dipole.
Where operators get caught
Let the feed line leave roughly perpendicular to the wire for a useful distance and keep support tension out of the connector or balun.
A better field procedure
Measure both legs from the electrical feed point, use proper insulators and strain relief, raise evenly, then trim only after the final geometry is stable.
Connector fit proves only mechanical engagement. Current product instructions, cable preparation, electrical role, weather sealing, structural load, grounding code, and the complete antenna configuration still control.
