Trichology Each led is 0.08w. So three leds is 0.24W. Current is 0.24W/12V=0.02A.

Shuflie Its to do with matching signal coming from the transmitter being picked up by the receiver, when a signal bounces of something the polarisation gets reversed. A RHCP antenna mainly pickups up RHCP signals and rejects LHCP signal which means if you are flying near something which will reflect a signal you only pick up the main signal not the reflection which gives a clearer picture. It also means that your transmitter and receiver have to have the same polarisation for their antennas.

Shuflie if you know what you're doing you can calculate ESR with the 2D42 or 2D72. You just need to pass a high frequency sine wave into the cap using the AWG, measure the AC voltage across the cap, and then calculate the internal resistance knowing the amplitude you selected for the sine wave and the fact that the output impedance of the AWG is 50 ohms.
