    My Dual band Antenna bought from local HAM shop.
    But we will install a new 7.2M Antenna for larger radio coverage.

    Thanks,

    If I overlooked your earlier post, I apologise. But my comment was referencing your last post and is still valid. A shorter cable may not make much, if any, difference and cutting the FR24 supplied cable may introduce signal loss.

    And please read all 919 of my posts here before you start making unfounded allegations about my motives or contributions.

    Thanks,
    Cool. Take your time to learn about all these flight tracking stuff. It's a lot in a very short amount of time. Enjoy the kit.

    The link can be found at http://goo.gl/n10t4Z and it is from Taobao.
    The result of new antenna is much better than my homemade antenna.

    For my case, the antenna is ship from FR.
    But I`m feeling that antenna is not a very good yet.

    Don't judge an antenna by its size. I find the antenna performs well, at my best line of sight it performs almost the same to my own setup. location with good line of sight is key.
