Petenz, were you tracking the Google balloons a few weeks ago? It was watching those that got me hooked on this whole ADS-B thing. Your receiver was really doing its job well!

are the (9 dBi) DPD antennas much of an upgrade from the stock FR24 model? I've been looking at their website and wondering if one of those and uprated cable would make much difference, if any.

Just watching a King Air head out the the Chathams'. That's the first time I've seen that.
And just as I was writing this at 2211UTC it disappeared.

As for the DPD. I upgraded to one from my DIY G7CRQ antenna. And gained a more stable outter-edge signal. Went from 130-170 to 170-200 range. But it seems quite comparable with the FR24 supplied one for a fraction of the size. I think its a 5dBPosts not to be taken as official support representation - Just a helpful uploader who tinkers

Unfortunately Taupo cuts out below 8-10000 or so. Maybe some day if no one beats me to it will think about getting something up by the lake. Still need to get my home WN antenna sorted before thinking about that. Though that will have to be over cell as no internet with batteries and solar, as power is turned off when no ones there.

For high gain antennas you can have a look here:
http://duplexers.eu/catalog/Pro/antennas/a10_1090/ <-10db gain
http://www.dpdproductions.com/page_vhf_air.html#adsbout <-9db gain
Personally I think the FR24 supplied antenna should be good enough. This is based on forums i read a long time ago about the SSE-SJ1090 Mk2 antenna.Last edited by North Borneo Radar; 2014-03-28, 04:20.

Originally posted by North Borneo Radar View PostI think in you case, getting the antenna to a cable as short as possible to the receiver would be ideal. Like a 1metre coax of H155/LMR400/westflex 103 something like that. You will have very little loss from the cable at that length. Well whether that is feasible is a matter to be considered. I am unsure whether you will gain much from using a higher gain antenna like the dpd 9db due to your unique location.

Perhaps you can contact FR24 for some input.

Well, I'm about to contact them to find out where my Premium subscription went!
Just bouncing some ideas really. It was someone who host a FR24 receiver in USA that posted here quite a while ago that he used a very short cable to antenna and had good range from it.
