Antenna Efficiency - Antenna Theory
The antenna efficiency (or radiation efficiency) can be written as the ratio of the radiated power to the input power of the antenna: [Equation 1] Being a ratio, antenna efficiency is a number between 0 and 1. However, antenna efficiency is commonly quoted in terms of a percentage; for example, an efficiency of 0.5 is the same as 50%.

Find height of the triangle (antenna) given angle of elevation and displacement from base > A man standing near a radio station antenna observes that the angle of elevation to the top of the antenna is $A = 63°$. He t...
$$\frac{\text{height}}{\text{distance}}=\tan(63°)\quad\text{and}\quad\frac{\text{height}}{\text{distance}+130}=\tan(49°)$$ therefore $$\begin{align} &&\tan(63°)\times d&=d\times\tan(49°)+130\times\tan(49°)\\\ \implies &&d&=\frac{130\times\tan(49°)}{(\tan(63°)-\tan(49°))}\\\ \implies &&\text{height}&...

Antenna orientation on a 4x4 MIMO capable access point A general rule of thumb for a 3x3 MIMO system antenna orientation is: 1. Keep the center antenna upright at 90 degrees 2. Keep the outward antennas leaned o...
Depending on your locale (upstairs, downstairs), use 90° orientation for current floor, 0° for upstairs, downstairs, and 45° for upstairs/downstairs, a bit displaced from where the AP is sitting. Have at least two in 90° position. It affects the polarization of the radiowaves, and it's often helpful...
