kgwilson Posted January 11 Share Posted January 11 Pretty much like any electronic receiver or transmitter. Signals are transmitted as wavelengths and bounce or are deflected of hard surfaces they cannot penetrate so get to the receiver obliquely. If there is a large flat surface like the side of a fuselage and the SE2 is behind it the signal is blocked. 1 Link to comment Share on other sites More sharing options...
RFguy Posted January 11 Share Posted January 11 the tubes and rag of aircraft size will not measurably affect it . the tubes are fairly small compared to a wavelength and will tend to just re radiate whatever they intercept. That being said, you want to stay at least half a wavelength away from any metal in the direction you want to go, about 15cm. The antenna is in the top half of the SE2, so you want that in the clear. flat plate larger than a half wavelength will start to hurt, though. The GPS is just as important, it needs a good view of the sky. (in the top of the box) . if you have a torx bit, take it apart and have a bit of a look 4 Link to comment Share on other sites More sharing options...

Neil_S Posted January 12 Share Posted January 12 Hi folks, Just FYI I had some friends in another plane check that they could see my Skyecho paint on their EFB from about 10nm away, and they confirmed they could. I could also see their Skyecho paint on my EFB from well before, so I guess that indicates that my Skyecho with its velcro/ziptie mount is located reasonably well. Cheers, Neil 2 Link to comment Share on other sites More sharing options...
RFguy Posted January 13 Share Posted January 13 10nm transmit range on a skyecho, is about the limit when the installation permits it. you'll likely see full power ADSB transmitters from at least 20 to 40nm away. again, depending on the installation.

danny_galaga Posted January 13 Share Posted January 13 Sorry to hijack, but I am entertaining the idea (My original plan actually) of getting a part 103 ultralight. While I'll just be pootling around in it and probably not navigating, would a sky echo still be worthwhile? I assume if I have that and nothing else, then at least it makes ME more visible? And obviously, with that sort of ultralight, I'd best be making a mount similar to bluesadventures, else it just winds up in the landscape below 😄 Link to comment Share on other sites More sharing options...

Just switch the internal details to the respective aircraft you are flying. Do you have. SE2 in your present aircraft? Link to comment Share on other sites More sharing options...

Not to mention up-to-date local maps, etc. (Minimalism plus peace of mind ;- ) Edited January 13 by Garfly 2 1 Link to comment Share on other sites More sharing options...

I already first tested my skyecho on my phone 😄 Mind you, you can't even fly 60 minutes at 100km/h in these things before you have to return so navigation will probably not be much of an issue!
