well i have a question. i put the raker i have on 1 and a half rat scrap pipe and the cold north winds blew in upper michigan and bent the pipe so that the antenna was tilted backwards about 30 degrees. now it might seem like a bad thing but with the bent mass pipe i seem to get killer dx. i got lots of dx from places never before unatailable. then went and fixed the pipe and can still hear them but not half as strong.. could it be conditions or am i onto something. i thought maybe that the bent pipe caused the signal to hit the atmoshere at a diffrent point causing diffrent dx. i know it sounds silly but lately thought i might just have to put the rat scrap pipe back up there... sam 123 upper michigan |

I've always put a lil tilt to my beam antennas and had good results. |

It sounds like varying the take-off angle is giving you access to shorter skip paths because of the steeper angle that the signal is reflecting from the ionosphere. |

ive actually seen guys that will purposly do that to their mast pipe and get great Dx results. Im sure someone will tell you different but hey if it works for you them "keep on ah keepin on!!!!" :-) |

hmmm, how about a rotor that can be adjusted to all degrees of angle, they already exist I think its spelled azimuth. |

Taz you'd have to rig a stacking boom to get it to rotate vertically front to back. I used a Yeasu AZ/EL [5400B] on a Cushcraft 10 M beam cut for 11. Which in hindsight I should have got a 12 Meter and cut it for 11, but that's another story. Anyway, I could rotate it vertically and have a vertical beam, rotate 90 and have a flat sider. Worked quite well, but didn't have the best set-up and it "saw" too much of the tower on the bottom side when vertical. Expensive move, but AZ-EL rotors are very cool. And now that I've thrown the thread outa whack...I'll move on! Good luck 123. |

Yhe rotor grabs thr boom instead of the mast that connects to the boom. It can rotate in all directions. Pretty cool I would say, a friend of mine runs one out here. |
