DH2VA you are not paranoid ....
you do not necessarily require a compass. With https://www.dishpointer.com/ you can find some prominent points.
QO-100 is 26E ARABSAT 5B......

Das wird aber ein blöde Rennerei
Die Antenne steht auf dem Dach der TRX ist im Keller
Das muß einfacher gehen sonst rennt man sich ja den Wolf
SWL? TRX im Keller? Hm...

Hast du die Empfangsantenne ausgerichtet? Wenn ja dann lass die Sendeantenne in die gleiche Richtung schauen ... - habe ich auch so gemacht .....

Hallo...
my test via QO-100 with a comparable antenna 35x35cm linear polarized ..
datasheet gives 21dBi...
DATE: some weeks after switch on QO-100 in march 2019

It might be interesting to see the radiation pattern of these flat panel antennas. Anyone has a plot?

This was just posted on the AMSAT-NA BB. I find it very intriguing especially in light of the current discussion around flat panel antennas for QO-100 uplink. https://vk6ysf.com/patch_Antenna_435MHz.htm

....yes everyone needs a sail...
Anyway, I like the idea of a flat panel antenna for uplink. It will be much easier to transport in a backpack for an ultra portable setup than a dish. That's what I am working on for my trip to Europe next year. Now, If I just could print a 3D foldable dish with metal coated cloth.....

Thank you!
Yes, that's the idea. I am actually looking at the coated camera light umbrellas for testing but ultimately like to build something. The dish option would work for uplink and downlink. The flat patch antenna would be uplink only with a simultaneous downlink reception via Websdr (eg., Goonhilly)

Hi,
new results with my flat patch antenna:
CW-carrier with 2W out and antenna handheld on balcony.
