Yagi-Uda antenna design vs Yagi-Uda antenna

Some examples from the web:

• We will implement the antenna designs one by one, beginning with the most popular antennas.
• If the element lengths should be modified for an individual antenna design, the display shows the length accurately for each element.

Some examples from the web:

• Get the antenna, get the antenna, get the antenna.
• This shall include the external antenna for mobile communication.
• Two alternative reference antenna distances are permissible:
• Antenna location relative to ESA under test
• The antenna array is completely fried.
• Each echo on the screen shall persist for at least the duration of one antenna revolution, but not longer than two antenna revolutions.
• Worldwide renowned antenna rotators for up to 2 m2 antenna surface.
• An antenna module for millimeter-wave communication.
• The benefit over a traditional omni antenna is that each individual antenna can be down tilted to the required degree, giving better coverage at the close vicinity of the antenna base.
• Further to the antenna gain you will experience a system gain of at least 10dB compared to the small built-in antennas by mounting the antenna outside of a building.
• The antenna drive system and the antenna shall be such as to allow correct operation at wind speeds of up to 100 km per hour.
• All antenna connections are BNC standard. Antenna electronics is in a weather-proof housing.
• HyGain antenna rotators are constructed with double or triple ball bearings for maximum stability and have electro-mechanical brakes which blocks the gear shaft, preventing the antenna to turn in strong winds.
• The antenna connector on the Radarbox is SMA, the supplied antenna comes with 3m cable.
• Any antenna may be used provided it can be normalised to the reference antenna.
• The field generating device(s) may be (an) antenna(s) or a plate antenna.
• My antenna never interfered with my old TV.
• This copper zigzag looks like an integrated antenna.
• I'm tuning her antenna, as it were.
• A satellite antenna can only record communications transmitted within the footprint in which it is located.
