    Well my coco is all taped up and in a conduit in the air just waiting until Monday when I can get some mcx connectors to plug it into the dongle. So what length did you cut the supplied antenna too ? I measured mine and calculated it to be a 1/4 wavelength.

    Just received my ADS-B dongle a couple of days ago, I am running it at Northgate about 8 kms from the Brisbane airport. I am just using the supplied internal antenna. I have started researching antennas and am looking at my first built antenna being a colineal coax using RG6 with a 16 element array. As you may have guessed from the name I ran raspberry pi's, I am reasonably competent with Linux operating systems having made the transition about 12 years ago and never looked back. I will probably post a few pics of planes at Brisbane airport also. As the ATC's say gedday.
    the supplied antenna that comes with the dongles isnt really optimized for adsb although it does work, i just trimmed mine down to the correct size but didnt notice much of a difference (am about 5km from YPAD)
    built myself the spider (non solder version) for under AUD$20, and stuck it to my old tripod and placed it on the carport roof, and it worked much better.

    going to attempt the colinier next, but for some reason avoided the coketenna and cantenna

    Welcome to the community PiRad108, I started out with a 16 element coco, it worked great, from about 37m ASL I was able to out to 350km or so... I have no idea how it stacks up compared with my current antenna in my new location though. Being 2mtrs tall and made from high pressure PVC pipe, it is a bit to floppy to put at the top of my upper mast section... Wish I could, oh well.. Which radar are you PiRad108?

Most of them, even those running for Qantas and Virgin are or have been owned by Alliance and they have always seemed to fit them with ADS-B before putting them into service, even long before it became mandatory. As far as I know the only RPT jet flying around Australia without it is a JetGo E135 VH-JZG. I'm not sure what it's story is but it always shows up as MLAT - one of very few Australian MLAT commercial aircraft on FR24 these days.
    I wasn't suggesting that there were any without ADS-B, just that for some strange reason I (and at least one other) was having problems getting any signals. Another example is shown in the attached capture. The 'ghost' was bracketed by other aircraft, so coverage wasn't the issue.

A day or so ago there were three outbound on the same SID, I got good tracking from 1 and 3, but the middle one was effectively invisible to me, although showing on FR24. Only seems to happen with F100s.

    zip. We did have F27s doing freight runs but they are all headed to you

    We get some of yours at times too, FK50 (-FKO) does tour group runs and when that is out the upgraded 70/100s from Alliance

    The latter do show up at times. Possibly only MLAT

    Here's a question for the 'over-Easters', do you have as many old Fokkers operating in various fleets as we have in WA?

    Supplementary question to all, do you find that an occasional one is very limited in ADS-B signal?

    Cheers,
    Ian on the Darling Scarp

    Yes, I've been rather quiet here, FA and on the Faceache group as well.

    T-YSBK22 has been chugging along without any issues (apart from the leak in my antenna a while ago) so I haven't really been looking at these forums much. In amongst working, running around after the kids with their activities (soccer etc) and a few other things, I haven't had much time to play with anything. Its sort of coming to a head though, as I need to replace my desktop PC as it's an old XP machine plus replace my file server.... lot alone doing things I *should* be doing like paint the house :-/

    Cheers,

    Andrew

    Hahah Yep, it's all your fault Oblivian! You ready to be blown away by Gita? Assuming she is still heading towards NZ?

    Wow, this thread slowed down a little!

    Hi NetRanger, welcome to the thread and feeding, hope all is going well.

    T/F-YBBN1 is run by Kemistry, he occasionally pops his head in here, though I've noticed lately that his PiAware feeder seems to have some stability issues?

    After a long absence due to a house move (to a much better locations in the same suburb), I've been able to get my feed going again, it's T-YBBN50.. My next project which will hopefully improve things slightly is to shorten my coax by putting the FA ProStick Plus dongle on a USB extension and upgrade from the old Pi B+ to a Pi3 .. I keep buying Pi3's then either selling as part of other jobs or finding other uses for them before I remember why I bought them

    Anyway Happy New Year etc! I hope all us Aussie feeders + Oblivion are doing well etc. Take care!

    Regards,
    Cameron

    For the north east NSW and south east Queensland feeders, I have just activated T-YEVD1 at Evans Head. Not sure if this will remain in position permanently (or maybe move to a better location) but it was installed primarily for the Great Eastern Fly In ( see http://www.greateasternflyin.com ) this weekend for ground and low level aircraft traffic to see whats about - if anything.

    Coverage favours the northern arc from South-west to East.

    Cheers

    Peter
