    I was just trying different designs and positions, using the coverage pattern provided by a weeks worth of "Virtual Radar" to get a comparison. (it is only recently that I realised I can get one of my signal generators to work on 1090MHz). Because of the shape of New Zealand and my location, there are parts of my coverage that will never see an aircraft.

    I don't think you would note any difference between 5m of good RG6 and 100mm of the same.
    According to one manufacturer, 30m of their RG6 has only about 7db loss at 1000MHz.
    In your case, any losses due to mismatched impedances and connectors are probably going to be higher than any in the coax itself.
    (actually, Until I looked at the RG6 specs just now, I thought RG6 coax loss was much higher)
    Your coax is made to survive the sun and rain, and I would definitely not guarantee my USB cable is going to last forever, so I would leave your system it is.
