text: However, the peak gain of an antenna can be arbitrarily low because of losses or low efficiency.
text: For example, a dish antenna on a spacecraft is a high-gain device (must be pointed at the planet to be effective), while a typical WiFi antenna in a laptop computer is low-gain (as long as the base station is within range, the antenna can be in an any orientation in space).
text: If the gain is low then its coverage is wider range.
text: The gain of the antenna is low because the small mouth approximates an open-ended waveguide.
text: The horn's gain is again low because the throat approximates an open-ended waveguide.
text: Such antennas are inherently circularly polarized with low gain.
