Will a bent director element affect performance?

    Give this some thought... We are discussing ducks here!

    Seems that everybody fancies himself as a comedian:D:D:D
    Actually, the antenna has very good SWR and seems to work okay. Mind you, I don't think the parasitic elements really have much effect on the radiating elements which are thankfully nice and straight.
    To be honest, I wouldn't even call it a bend, it's more of a slight curve upwards. I think it's probably best left alone. I'll do some operating and see how we get on. At the moment, we've had so much bad weather and strong winds that the antenna tower is right down so the beam is barely 30 feet above the ground. Once the winds die down I'll crank the tower right up and see what happens.

    I checked; it's SHORTER than the other. What now?

    I totally agree, and that's what I said on my original post also.

    I don't have ducks, I have chickens.

    7 of them, 6 hens and a roo.

    My antennas are way higher up then chickens can fly, as I find they (the antennas) work much better that way.

    Rege

    P.S. I have "free range, cageless, organic West Asheville eggs for sale (to offset my radio addiction)

    For a limited time, I am offering them for sale (the eggs :)) at my co$t.

    $2.85 each fob Asheville NC :rolleyes::p

    If the element was completly missing you would loose about 1db. So a slightly bent end director might affect the main lobe but very little and at worst 0.3db i wouldn't loose any sleep over it.. You can do a simulation on 4nec2 and enter a bent element to match yours, i doubt it will even be noticable... Get it powered up and forget about it..

    That is nothing to worry about. Rotate the other way for the next wind storm or big bird collision.
