...also because my first helical antenna I built it exactly 42 years ago, for AO-7.
Remco, in my garage I have already built three antennas, with different solutions. With more turns and with less turns. At the end I will decide what to mount in a fixed place. This one of Winkler will serve as a reference, or I will modify it. We'll see what to do.
In any case, there was no mention of G8HAJ's backfire helix.
With P3-E unfortunately no progress. The hoped launch opportunity in US did not materialize..

maybe we can ask a ride to Elon Musk for the next test flight. Together with Tesla our satellite would be in good company.
the photo I put is taken from that forum. Maybe I should report it. I ordered this helical feed but I have not received it yet. When it will be in my hands, we will do some measure. The mechanical solution seems good and also economic.@IW9EZO
Forse vanno svitate quelle due viti, tolto il collare, avvitare il connettore e rimettere il collare. Come dicevo non è ancora arrivata e quindi le mie sono supposizioni.
I wanted to try the program but unfortunately it crashes as soon as I open the device.
there is another channel on this transponder that writes in Arabic and I do not understand anything.
The only thing I understand from the promo is that the broadcast will begin on 01/31/2019.
For what is public news, Melco delivers the satellite to the customer by January 2019.
If two plus two makes four, Es'hail-2 begins the official activities on January 31, 2019.
every country writes it in his language...
I scan the transponders at least three times a day. There are other "anonymous" transponders and the first one was 11270H.
This transponder, 11350 H, is not yet completely configured and therefore we do not know "officially" who is transmitting it but ...
The channels it is broadcasting clearly indicate the frequency, the parameters and the satellite.
I really like this solution. This ensures us a good stability on the downlink. But what happens if an uplink station is not stable in the same way? We are forced to follow the correspondent and our reception stability is relative.
only change required by the user is to change output connector from RP-SMA to SMA. 5 minute job. 33 dB gain up to 15W, no compression yet to be seen. 12V input @ 5A max.
from the notes in the insertion it seems a heatsink is necessary for powers higher than 5 watts
- Electric current: 12V 5A
- Please add extra radiator aluminum fin or fan when the output power over 5W
- Please connect the antenna first then supply power, finally connect the signal device."
maybe wrote it and I missed but I did not understand what LNB are you talking about?
If it's the Octagon can you put a picture of the label on the LNB?
official NB transponder. we have an extra bonus
Yes, WB Transponder is ON
we begin to take measurements.
My center band corresponds to the end of the NB transponder.
A correction of 125 kHz should be applied.

NB Transponder ON 10489V and CW Beacon
Now in JN61FQ
Same in 10706 V
