Lightning radars
I have make a lightning radar long range 2000-3000 km over the land,and more over the sea .The original consept and design is from Frank Kooiman. Here i have photos how i making,the design of the electronic circuit is from Daniel. Here it is my Lightning radar data.Lightning Radar Data

Here is how start to make the antenna loop.I use 3 woods 2,5 x 2,5 cm ,and two of them horizontal it have lenght 105 mm,and third vertical 140 mm,because it need little more lenght for base keeper I use 8 angle bracket for keep the antenna cable,3 screws 4 mm and lenght 6 cm,6 nuts and 3 washers. The distance where i put in the wood vertical-horizontal the angle brackets it is 100 mm

Here i use one-ply cable 1,5 mm diameter, 25 + 25 meters every loop. Antenna loop is allready. Here i have start to building it the first place i make a power supply for the lightning radar amplifier.

Second lightning radar
I have make and a second Lightning Radar and second antenna, for to have it and to make some experiments about sensitivity ,and low noise .

Here it is the aluminium box ,switch on-off,antenna conector,jacks and black cable for sound card ,220 volt white cable 2 x 0,50 mm . Here it is the electronic parts and 2 PCB, one left side for power supply,and second right side for the regulator voltage and the amplifier. Here i have open holes and i have put over the box ,switch on-off,antenna conector and 2 PCB

And here the same like before The first part to invert voltage AC-DC it is ok .There are 2 voltage power, positive voltage about 20 VDC ,and negative voltage about 20 VDC. And here it the resolution at left multimeter it is the positive voltage ,and the right side,it is the negative voltage.

Here it is ready the second part the regulator voltage ,There are 2 voltage regulator power,positive voltage 11,5 VDC ,and negative voltage 11,5 VDC And here it the resolution at left multimeter it is the positive regulator voltage ,and the right side ,it is the negative regulator voltage. And it is ready

Another two Lightings radar amplifiers over PCB double layer
I made another two Lighting radars amplifier for to give at two weather friend here to Greece .

Here it is two pcb double layer and the electronics components for the one amplifier . Here i am near to finnish it. The same,little near view

Here it is ready the first amplifier,yet i do not have put at case the two microcircuit OP 27 Here is absolutely ready . And from the other side.

Here it is ready and second aplifier over to PCB double layer . and from the other side. Here i make a test,with my second antenna,one transformer 12 volt AC,and work fine.
