My FA 1090 antenna and 1m cable should show up any day and I will be making that change at one of my sites soon. My other concern about coax into the house is bringing lightening in. We get a LOT of bad thunderstorms in Texas so it's a real consideration. I have lost more electronics to lightening strikes over the years than I care to admit. I know there are high quality suppressors for LMR-400, but between the insertion loss there and the run of coax, I am leaning towards sacrificing a Pi0 and it's power adapter up at the antenna rather than making a conductive conduit back into the house. If I lived somewhere else the trade off would likely be different. Thank you for the discussion. M
LMR400 is expensive? Obviously, you haven't purchased coax or feedline recently. LMR400 is a great price for what it is (the knockoffs like Terrawave's TWS400 are equally good). When it starts costing >$10/ft. (like AVA7-50), then it's just starting to get expensive.
Nice work superg3, some impressive stats. I would certainly be interested in your tutorial, if you have a RPi3 in the box on the pole It will be interesting to see how you keep it cool as well as weather proof. Best Regards. Colin
Hi all, Very interesting, are there any drawings/ specs. for both COCO and the plus? Would love to have a go at this one. C

Thanks, Have it all stashed away nicely ready for when I can get to spend some time on it. Very much appreciated. C.
I have a 9 element coco antenna I made out of RG214 cable mounted at the peak of my house. With a Flightaware Pro dongle and a RP3 I am getting 200NM+ range. My feed line is about 30 feet of good old RG6 coax, with F connectors and BNC adapters. ETA: I plan on mounting the Pi right at the antenna, to see if the range is better.
I can't post a link here, but my feed is /?feed=JFUx1luNXAQY Add global DOT adsbexchange DOT com to the front of that.
