Why put the fragile antennae at tree branch height?

    Sometimes my assumed role as a tree trimmer trims my truck's branches too.




    Oh, so moving them lower would make them less receptive than ripping them off? Sure. If it makes that much of a difference, then put them on the roof, behind the aerodynamics, so the base is protected.

    Is this a serious question? The same reason cell towers are way up in the air and satellites are in space

    Personally the only time I've broke a anntenna was in freezing rain..they are normally pretty durable unless you buy the cheapest ones

    I used to set my antennas to the height of my trailer, usually 13'6" Very handy to slowly go up to an obstruction(bridge, canopy etc) and if the antenna's are hitting or close, another trailer saved from damage. Decent quality antennas with a decent mount will survive the abuse.

    It has to do with radio transmitting capability, and maybe reception on a tall vehicle from all directions, putting it out there away from the cab and getting it as high as possible, without hitting something and breaking.


    The newest trucks have concealed antennas and I see lots of mirror brackets and antennas being added to the trucks by those who care about a useable CB.

    I always tilt my antenna forward just a bit, that way when im going down the highway it will stand straight up more instead of being blown back, if that makes any sense, I cant explain it well, lol

    The reason that cell towers are up high is because of the nature of the frequency that they operate, it is called line of sight and the higher the better. The reason that satellites are ... well orbiting the earth is to cover as much distance consistently as possible, allowing one radio signal at one location to be repeated to another location far away.

    The reason for putting the antenna above the cab is to allow the signal a clear path, there are null spots with any antenna with any vehicle where the signal is less then another direction. The truck moving makes it seem that there are none.

    Putting the antenna forward does nothing other than making it a great way to snap off the antenna when an obstacle hits it.

    Not in my line of work they don't. Internet shoppers who are too lazy to trim their trees have a tendency to wreak havoc on just about any manner of CB antenna.

    I've hit my Wilson on several trees every day. The only thing it took off was the top cap. But the swr is still good

    Good grief. I would think if you had to protect the base, the truck is probably somewhere where it shouldn't be.
