    my current vans always had sh/tty radio reception. i renewed the roof aerial....no good, twice ,,still no good. then i had the idea-maybe the aerial needs to be higher than the ladders to work well.
    Photo-0009.jpg . to prove the point i made up a long aerial using a 4ft bamboo cane with bell wire wrapped around it [bottom end of wire goes into place of the original whip aerial

    RESULT! Great reception i can hear stations many miles away clear as a bell now

    Better way would be to expose the wire of the aerial and run a copper wire from it to the ladders on the roof, if done right the ladders will act as an aerial and improve signal

    Have you tried this^
    A whip antenna is the standard omni directional radio antenna

    Ive used the principle before. Was a infantry signaller for 4 years, used to use barn roofs, or anything big and metal to boost signal on HF radios. Used to listen to bbc radio on it when not using it so should work in theory

    Clisty you would know about coiling a few metres of insulated wire around a pole of some sort to make a small pole act like a few metres of arial
    I have done one with about 30m of wire round a broomstick wrapped really tightly
    It is in effect a 30m aerial..if it's already high enough on a roof to avoid obstacles you will be able to get any pirate station for miles crystal clear
    That is how the pirate radio aerials were done on our estate lol
    I have used my ladders as an aerial in the past effectively

    True, just thought it would be less obvious and draw less attention, and takes seconds to rig up, plus im lazy and its easier

    Unless the ladder was vertical I can't see any advantage over the bamboo whip antenna
    Plus you'd have to remember to decouple each time the ladder was off?

    Surface area
    If you are only getting a slight signal reach your skinny aerial a bigger surface area would catch more of the weak signal due to the size of it

    All to do with the area of metal and the way radio ways travel. The science is a nightmare and will give u a headache. In my attic the theory fills 3x A4 notebooks!
