Small overview-unpacking FPV 5.8 GHz 600 mW TS832 + RC832

Good evening everyone. To your attention there will be a small review-unpacking FPV 5.8 GHz 600 mW TS832 + RC832
The parcel was delivered to the door by the meest-express postal service 16 days from the date of dispatch.
Here in this form the package arrived.

Inside we find a neatly sealed receiver and transmitter + cable. An additional cable was ordered for Hero3.
A little photo shoot of the insides.

In appearance, everything is neatly made and folded.
Video unpacking.

Now the fun begins, a couple of tests.
I used a conventional dome camera (having previously pulled the camera itself from the housing). 12 volt camera.
The apartment worked flawlessly.
Made a measurement of currents without a connected camera. It turned out 342.4 mA at a voltage of 12 volts. The instructions say that it should be 220 mA. Tell me what happens.

It was noticed that the transmitter warmed up well in 5 minutes. Made measurements.

After a couple more minutes.

Pretty well heated near the antenna, about 80 degrees.
Slightly disassembled the antennas. That's how they look disassembled.

Tell me how to understand they are at 5.8 GHz.
And finally, I measured the approximate rangeon the ground. The receiver threw out the window and started moving from the apartment to the street and in a straight line. Visibility can be said direct, but sometimes buildings and trees interfered. As a result, it turned out that he advanced 300 meters.
Here is a video of a trip with a camera.
While there is no opportunity to test in flight.
The goods were bought for their money.
Thanks for attention.
