A side-by-side table of every gps / gnss 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 2 to 35 dBi while the longest dimension moves from 3 mm to 1100 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.
