Which is Better – Horizontal or Inverted V Dipole?
Neither antenna is universally “better” — the right choice depends entirely on your available physical space, the number of tall supports you have, and your operating goals (DX vs. regional contacts).
Here is a quick visual difference between the two setups:
The Horizontal Dipole
A standard horizontal dipole is strung in a straight line between two supports.
- Radiation Pattern: Produces a classic “figure-8” pattern. It pushes signals out broadside (perpendicular) to the wire, with deep nulls off the ends.
- Impedance: Typically around 73 ohms at its resonant frequency.
- The Catch: To get that perfect figure-8 pattern and a low angle of radiation for long-distance DX, the antenna needs to be at least half a wavelength high (1/2 λ). It also requires two equally tall supports (like two trees or masts) and takes up the maximum amount of linear space.
The Inverted V
An inverted V takes the center feedpoint and hoists it high on a single mast, while the legs slope downward toward shorter ground supports. The angle at the apex (center) is usually kept between 90 and 120 degrees.
- Radiation Pattern: The sloping legs make the pattern much more omnidirectional compared to the strict figure-8 of the horizontal setup. You lose a little bit of broadside gain, but you fill in the nulls off the ends of the wire.
- Impedance: Bending the legs closer to the ground drops the feedpoint impedance. A well-tuned inverted V often sits right around 50 ohms, providing an almost perfect match for standard coax without needing a specialized balun or tuner for matching.
- The Catch: Because the ends are closer to the ground, there is slightly more ground loss. The radiation angle is also generally higher, favoring regional NVIS (Near Vertical Incidence Skywave) propagation over ultra-long-distance DX.
Key Insight for Lower Bands: Getting a horizontal dipole to the ideal 1/2 λ height is relatively easy on 20 meters (~33 feet up). But on the lower HF bands like 80m and 160m, a half-wavelength is 130 to 260 feet in the air.
Because achieving that height is impossible for most home setups, an Inverted V becomes the overwhelmingly practical choice for low bands. It requires only one tall center mast, fits inside a much smaller yard footprint, and nicely matches a 50-ohm 100W transmitter.
