cheap sat LNA VS cheap TV amp xD

YES, got the power inserters finaly !

the test setup.

On picture one ,you see the setup i use on the atic.

Rpi, with rtl dongle, in combo with a cheap TV amp (not for ADSB freq xD)

On the below picture is my test setup

it has a airspy receiver with a SAT inline amp

the antenna is the same, only it is 3 meter lower as the antenna on the atic.

And finaly, a combined view in VRS

The Magic it self

he is here.. the airspy one.

ok, and now ? ,what is the result of it???(update2)

Plaines receiving with dump1090 on a Rpi

 

Well, it seems that moving the antenna to the atic was not a problem.

getting proper cable also no problem.

but what is the problem ?

1st picture.

antenna on balcony with NO amp.

2nd picture.

antenna on balcony with AMP.

3th picture.

antenna on atic (but 30meter cable) NO amp

*sigh*, what a fail

4th picture

antenna on atic (but 30meter cable) with amp

*sigh*, still a fail.

5th picture

antenna on atic (but 30meter cable) amp just below antenna

*sigh*, still a disapointment.

Ok, so, this is a fail.

yes, i do receive now planes from the west , but i lost a shitload on the east when antenna was outside on balcony.

guess i have to play with the place where the antenna works best.

P.S
did i mention that the amp is actualy for TV signal use only?
that is as, 50-950 mhz..

need to get a LNB DC injector, so i can test with a ,hm, proper AMP.

(UPDATE)
Well, it seems my 2nd idea wasnt bad at al.
just give it a hour, and after move the antenna to a better spot.
the results are interesting.

This the plane outcome after 1 hour with the new situation.
yes, lesser planes in the east (germany)
yes, more planes now in the west (belgium)

situation after moving antenna 1 meter to more free space.

The best i can do is wait another hour to see the results, and post it.

(UPDATE)
wel, i am not i for waiting a new hour.
20 minutes later i took this screenshot.

i am fucking impressed now !

Experiment did worked afterall.

 

3th version ADS-B antenna SATcable direct feed.

My 3th atemp to make a 1/4 wave ADS-B antenna.

What is wrong with the others ?

nothing, ex that each version gave beter performances.

oh, please, tell me, how do i set a BLACK background,..

Stuff used for project.

2 paperclips for making 4 ground elements.

10 meter high grade SAT cable xD

lots of coffee and fun, and a telefoon that need a hamer to trash

god, i hate wolfgang smartphones.

2nd PS, how do i change the blabla in something usefull, hehe. 

Bend paperclip, should be around 16CM total lengt.

any more, CUT (or not)

CUT to 8cm (4x)

6.8CM length for ground element.

Bend 90 degrees

remove shielding till 6.58CM

stick ground elements in cableshielding (yes that works)

Should look like below xD

Bend to 45 degrees xD

this was my framerate with my old GP (TV cable)

this is it with the new 1/4 GP

After 5 minutes that is.

My 1st ADS-B antenna atemp xD

My 1st atemp to make a ADS-B antenna.

To be honnest 1/4 dipol worked nice.
