I’m testing a DYI VHF/UHF Moxon antenna for my station 858. Fixed elevation about south and an elevation of… maybe 45 degree. I will run this a couple of days, daytime only.
The RPi is powered from an USB power bank.
Plan is to install a VHF/UHF (or UHF only) yagi with fixed position, in order to make it possible to decode data from satellites from my station.
This 3 el X-Yagi performs well, the best antenna so far I have tested for SatNOGS (and I have tested many…). Thanks to @pe0sat for support.
The antenna will now be mounted on the roof with a broadband LNA so station 858 will now be offline for a while. Also I have vacation and there has been some thunderstorms the last days.
I’m sorry to say that this construction failed when I mounted in on the mast/roof. It was a bad construction mechanical. Phasing cable for RHCP broke. Coax cable connection to the driven element was unstable. Also the antenna was to narrow in bw. When built correct I still thinks this is a good antenna.
Next attempt will be a dk7zb design with better material for the driven element and directors. As i know station 858 is used by many I have a goal to provide a better s/n on the UHF band from my station.
