Technical Support / Rosetta / Sky Demon / uAvionix AV-30 combo

« on: August 03, 2023, 02:00:13 pm »

Hi All

I’m currently happily running a Rosetta with traffic display on SD. I wish to install a uAvionix AV-30 EFIS. This can also display traffic (via a wireless link device ‘AV-Link’) from a GDL-90 source.

Questions for anyone who has already done this (or just knows the answers!):

1) Does the Rosetta transmit a wi-fi GDL-90 signal that the AV-30 can use to display traffic?

2) Would this display ALL traffic (PAW, Flarm, etc., as SD does) on the AV-30, not just ADSB?

3) If the answer to 1) is ‘yes’, can the Rosetta ‘talk’ to SD and the AV-30 simultaneously? I.e. happily display live traffic on both devices.

Many thanks for any useful comments.

OGN-R PilotAware / Antenna ground plane

« on: January 25, 2022, 06:04:16 pm »

I’ve completed my ATOM-GRID installation and it is online and working. I have a question about grounding.

My very basic knowledge of an end fed monopole is that one side of the feed is connected to the antenna and the other side to “ground”. My question is, does this ground have to be physically grounded (earthed)? This is particularly relevant to the PAW antenna as it incorporates a ground plane.

In my installation the antenna mounting pole is insulated from earth – not by design but because the pole mounting brackets are fixed to the side of a brick building. There is no earth going to the electronics (in a plastic box) as the PSU is POE.

Would there be any benefit in earthing the mounting pole and thus providing a ground to the coax outer?
