Electric power is the rate at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt (one joule per second). Use this tag where power is a primary concern for the design under discussion. Use the "low-power" tag when that applies.

Just I want to understand gain, power, link budget
I am a beginner, I am confused about calculating the nessecary gain and power and sensitvity to overcome path loss at certain distances.
the first thing what does gain mean ? … is just adding gain to last output power to antenna gain right ?
or we just adding the total gain of amplifier and antenna and ignoring power ? …

If I connected N numbers of amplifiers each have X gain 'dB" and Y power "dBm", how to calcu...
If I connect for example 3 amplifier , each one has 60 dB gain and 15 dBm power.
can we say simply total gain is 180 dB and total power is 15 dBm ?
or I am wrong ? …

What is an antenna amplifier ? How does it add gain?
Or does it mean the Tx power will be 20+60=80 dBm ? I am confused ! … Or should we just calculate the resulting power at repeater instead of its gain ?
Do we write (-30 "Tx"+ 60 "repeater")"total power" + 10"antenna" ? …

Is possible to use wave guide to decrease beam width?
If I use a normal 1/4 monopole antenna "30 MHz for example" and cover it with metallic wave guide has a narrow beam width, should the gain increasing according to this formula below?
$$G = 10 \; log …
