I found this Luna lander on Twitter at random, feel in love with it, but it was too small (go big or go home, right?) So my son @wizradical worked his mad math and CAD skills on it then spent almost 48 hours printing it for me.
Totally love it. Great upgrade to the living room.

Huh. After alexsystemf comment I discovered that I had not posted a coverage map for yonks... So here is a low quality screenshot of our satellite ADSC aircraft.

Checked the focal point of my dish. Sure enough, it was a fair bit out. No before photo, but it was the size of a family sized pizza pan. Now that it's much sharper, the tracking is more critical, but 6db is worth it. Right?

Since the antenna shootout was just about patch vs helix (and because Instagram is useless for multiple image posts from any source) here is a screenshot of each.
In short, a 7 turn helix is quite a bit better than the patch. Zero surprises there.
I am thinking about building a few if the helix and selling them since there is a lot of interest in L-Band SatCom ACARS.

Antenna shootout. The #rtlsdr V1 and V2 patch and 2 3D printed (thanks @wizradical) 7 turn helix. One with mulit core wire and the other 4mm copper pipe.

Yay. After years of guessing @nooelec have finally started putting labels on their LNA ports.
It's the little things.

How adorable is this little helix!!!!
Can't wait to test it out. L-Band SatCom. All the data!
BTW, it's a highly portable station concept only. (Or if you are an apartment dweller).

Spent a good part of today installing the 24 inch lazy Susan under the dish to add azimuth tracking.
#nodered gets the TLE from #celestrak and we now track both axis.
Lots of tuning and dialing in the rates, but we should see better 1200 burst #ADSC rates each day.
