Hi, thanks for the answer. Yes i used the guide from qsl, beside of some others. Details about the dipole length/etc. is in my first post. The frequency band at 137.9mhz is nearly empty, no interference apart from some noise created by the voltage regulator from the LNA. But this does not affect the signal strengthsnn47 wrote: ↑Sat Apr 20, 2019 3:08 pmDid you use this double cross antenna design https://www.qsl.net/l/lu7did/docs/NOAA/ ... MARTES.pdf ?
I'm experienced at soldering. I even pre heated the 4mm2 cooper wire before applying the solder
What confuses me, is the fact that the antenna works great in the northern region, decoding passes with elevation of <10 degrees is possible. But as soon as the satellite reaches the south, the signal strength drops to a unusable value
I think the next step would be to reposition the antenna? I will have to buy a new coax first, since the old one is not removable from the roof
Ps.: Again, north is marked red on the antenna
