Stacking Yagi Antennas

Stacking Yagi Antennas Compared: Gain, Beamwidth, Size and Connector

Stacking Yagi Antennas — Stacking two or more Yagi antennas and feeding them in phase increases
Stacking Yagi Antennas

A side-by-side table of every stacking yagi antenna in the catalog, sorted so the gain-versus-size trade-off is visible at a glance. Higher gain on the same band always costs aperture length, and on a mast that length is a wind-load number, not a footnote.

The trade-off in one sentence

Between the smallest and largest model here the gain moves from 1 to 23 dBi while the longest dimension moves from 3 mm to 2570 mm. That is the whole negotiation: roughly every 3 dB of additional gain doubles the effective radiated power in the main lobe and costs about twice the aperture.

Reading the table

  • Gain is referenced to an isotropic radiator (dBi). Subtract 2.15 to compare against a figure quoted in dBd.
  • Beamwidth is the half-power (−3 dB) width. Coverage does not stop at that edge; it is simply where the signal has fallen to half power.
  • VSWR is a band-edge worst case. At 1.5:1 about 4 percent of forward power is reflected, which is negligible next to a typical feedline loss.
  • Length is the number that decides the mount and the wind load, and it is the constraint that most often forces a lower-gain choice.
