    I did all my antenna testing in the loft. I have cement tiles and found I got an extra 20nm once the antenna went outside. When you have something that works well, start thinking about how you would get it outside. Your location will ultimately decide your maximum range and "hits".

    Absolutely agree mate, .... until things go wrong. The SSE 1090SJ that you gave me has failed (could be the amp- the injector has tested ok as it's here inside the house) and I need to test and check the amp- on the 30' mast atop the ridge capping installed by the professional TV guys. Looks like the cockies, corellas and galahs have been busy 'enjoying' chewing my setup. The 'boss' wont let me climb up on the roof so I'm not too sure how I'm going to proceed from here (don't want another spell in hospital). So for now I'm back on the Discone with limited range. At least it keeps me out of the boss's hair for a while sorting it out.

    Regards,
    ... and there'll be an answer to it somewhere, sometime I'm sure,

    So....getting back to the original post 224 pages ago.

    What are the top rated 2 or 3 ADS-B antennas right now? I have moved and do not have the space
    for homebrew so they will need to be store (web) bought.

    Thanks
    Ken

    Ken,

    As I indicated in my last post forget a Discone as it's a broad frequency spectrum antenna not designed specifically fo ADS-B, whereas the SSJ 1090 is and you'd get far more range. As mentioned both on this and other threads it is discontinued but if you search you'll find links to antennas designed for ADS-B which are currently available. The type of receiver you have can also have a bearing on what best suits your situation. There is a thread for best purchased antennas (current) so I'll post the link when I can find it.

    It's also important to match the amplifier (if used) to the antenna. With my setup I cant use the same amp with the Discone as I can with the SSJ1090 and vice-versa and expect the same results due to the SSJ having a DC bridge whereas the Discone doesn't.

    Regards,

    Thanks for that, I can't believe my own stupidity! I simply hadn't ticked the receiver range options in the map menu!
    Here is a 72 hour plot.
    Circles are 90 nm intervals so I'm happy with this - the radio line-of-sight distance to the East for aircraft at 40,000 feet is around 250 nm so I'm not going to improve on this whatever I do. I calculate that to get the same range to the west my antenna would have to go up another 250 feet or so to see over the hills.
    Many thanks for all your patience and help.

    How about these new 222ml coke cans that have hit the market? ... seems Coke might be phasing out the 355ml cans in favor of them but keeping the price the same
