    IMHO try all three combinations ie both then red then blue and see which gives you best reception. (if it works )

    The reason I say if it works is that maybe the original aerial is made to a specific size and length as nonmally I believe they are "tuned" to the device.

    Great idea. Mine goes inside this winter. Less chance of people swinging themselves aboard by grabbing it, as well.

    my antenna was the tubey thing also and it also got full of water. Dried it out carefully with a hairdrier then sprayed the whole thing with circuit board lacquer and it all worked fine.

    The connection however, is a 50ohm co-ax which also carries the d.c. for the active antenna. I used RG58 but put a 75ohm TV plug at the receiver so I'm a little amazed it works!!!! but it does.

    I've a navtex target receiver without an antenna. May I use a other antenna. What's inside the original active antenna from nasa ? Are there diagrams to find from the circuit inside the antenna? regards
