Gain:2.15dBi(144MHz),5.2dBi(430MHz) / Max.power rating:70W
Impedance:50ohms / VSWR:Less than 1.5:1 / Connector:MP
Type:1/2wave radialless(144MHz),2x5/8wave radialless(430MHz)

Thank you

There is already a VHF Vertical and UHF Vertical antenna in the list, which reflect your antenna closely enough.

I really don’t see the point of the huge list of antennas currently present, which mostly represent similar things (vertical, yagi, turnstile, etc…) just with slightly different frequency ranges. It should really be a frequency range (or a set of ranges), and a custom description field where the operator can provide details.

My 5c+GST.

https://gitlab.com/librespacefoundation/satnogs/satnogs-network/issues/594 has a suggetsed feature for reworking how satellites are defined.

I’m just getting into satellite reception, and as a newbie I would find it interesting to see statistics on which antennas are able to get the most decoded messages, sliced by the types of satellites and frequencies I am most interested in.

Hi,

It is not a complete answer to your question, but you will find interesting information in the following threads:

Station Demoded Data Az/El Plot with data until 2019-09-18

Bellow you can see az/el plots by https://gitlab.com/kerel-fs/satnogs-AzEl-plots script of @kerel based on @pierros initial script . Data used for these plots were extracted from satnogs-network and can be found in their csv format in this zipped file: 2019-09-18.zip (9.4 MB) . So in this diagram you can get an idea on which Az/El a station performs good enough to demodulate data. Have in mind that the sum of data (colored areas) are shown in logarithmic scale. Data includes one entry for eac…

Complete satellites list based on observations

Hi all, Is there a way to get a list of satellites with percentage of good/bad observations? And possibly sorted/filtered by date? I would like to make a list of satellite easy to receive now, so I do not care about satellites heard last time months ago. Of course, I would like to see both decoded and not decoded one. In the list available in the statistics, I think I can only see the decoded one. Any suggestion? Tnx! Alberto

From there, you can dig a little more to get partial answer to your question.

N5FXH,

Split antenna and frequency field (#594) · Issues · librespacefoundation / SatNOGS / satnogs-network · GitLab has a suggetsed feature for reworking how satellites are defined.

Indeed there is this issue some time now, I’m planning to fix this in the next days.

Hi Mark
I hadn’t realised I could just add in from the list , I thought you had to tell Satnogs specifics for some data collection about antenna types etc. Have changed this morning as you suggested.
Perhaps a better way is for a frequency range and a comment on the station page of vertical , dipole , Helical etc ? Also have the list by hf , vhf , uhf etc then the build type instead of one long jumbled list ?
As always great support from the satnogs community, looking forward to the iss sstv pass later today over Nz
