Technical Support / Re: Nearer of further....location of underbelly antennas

That's excellent info, thanks very much Peter for making sense of the subject of SMA standards.

I'll see if I can get a suitable cable to minimise the amount of adaptors that I seem to need now......

A quick update, just read this string again to see where I had got to.

The Wiif was OK after reloading the software (though that might not have been the problem) and the unit was working fine, still appearing on FR24 as ADSB.

Every two months I E mail Funke to see if there is any progress on the software upgrade, last reply was sometime soon but that was in January so I just gave them a nudge to see if they have any progress.

Aside from that just fitting out the exterior antenna's ready for when we all take to the skies again!

Regards, Clive

Hi again Clive,

The SMA connectors used by PilotAware are all ‘Standard SMA’ - i.e. the ‘female’ has the external thread for attachment of the ‘Male nut’ and a recessed ‘receptor’ inside to receive the male ‘pin’. Both connectors fitted to Rosetta are ‘Female SMA’ connectors. The standard Rosetta antennas are both fitted with ‘Male SMA’ connectors, with the male ‘pin’ in the centre and an external ‘nut’ for attaching to the female.

The opposite type - often used for WiFi routers - are known as ‘Reverse Polarity SMA’, with the ‘pin’ inside the externally threaded female and the ‘receptor’ inside the captive nut ‘male’.

Hope this is clear enough.

Regards

Peter

That was my thinking too but thought maybe the filtering would handle it and maybe the transmit would be better further away from the TXP.
I'll go the way suggested above and see how it works.

The other challenge is the finding the SMA connection with the pin in the right end, female/male with pin or socket, trying to figure the terminology to get the right one, anyone know how to differentiate? Currently going by the pictures....

Just back from the airfield and brought everything back except the PA transmit antenna, can anyone tell me is the pin in the antenna or in the unit?

regards, Clive

Hi Clive,

It is always good practice to try to maintain as much separation as possible between any antennas, though this has to be balanced against the space available and the downside of using excessively long coaxial cables. Based on practical tests which I carried out over the past year with external antennas under the pod of my flexwing, however, I certainly support Paul’s recommendation to keep the PAW 1090 Receive antenna as far away from your transponder antenna as is reasonably practicable.

Let us know how you get on.

Best Regards

Peter

From similar questions I've asked in the past, it would seem you are best mounting the ADSB antenna as far away as you can from the transponder antenna. This is because the transponder will be transmitting and receiving on 1090MHz and your poor ADSB antenna (receiving on 1090MHz) is going to get its ears blasted by a transmitting transponder.

Hi folks, I'm installing proper antennas under the belly of my aircraft and have an option as to which of the two goes nearer the plane's TXP antenna, this is mounted off to one side so using the same position for the transmit and receive one will be nearer the TXP antenna than the other, which is best where?

Thanks, Clive

OGN-R PilotAware / Re: METAR feature in latest software??
« Last Post by steveu on April 18, 2020, 03:44:36 pm »
Current  METAR upload to Skydemon from Groundstations ..now wouldn't that be something!!?   :)

Skydemon already gives weather displays if connected to the Internet - we sacrifice the Internet for the wireless connection to the PilotAware.

Another option could be for there to be a METAR page to look at from the PAW Traffic display, one button for showing the local METARs.

It's interesting that a sister network, the Burnair Skynet in Switzerland, a FANET based network already has weather to upload to the Internet and to all instruments running the FANET protocol.
