Any tech or any person that can help. I have a dual band 2 meter 70cm beam antenna and a 11 meter beam. What I want to do is use these 2 beam's on the same mast same rotor on the tower. HERE IS MY QUESTION. When I stack the ham beam over the 11 meter beam how far should I space the 2 beam's apart for the best performance??? |

Personally I would leave a space of a quarter wave of the 11mtr antenna between them , more if possible. Bear in mind you will have to adjust BOTH antennas for optimum SWR after you have them stacked and not before.

I understand. People having no time at all, busy trying to make it. Times are hard in this country People including our leaders love the evil hate the good. call good evil and evil good. This is in the bible. My ancestors are from Scotland. Maybe its time to move back. But anyway Thank you so much for your help . You and your family have a Blessed day. |

The fact is, the 2m beam is so small, it won't affect the 11m beam much at all. Be thinking of the 2m beam spacing from other stuff. A half wave on 2m is just over 3 feet. A full wave is just over 6 feet. So, go with 6 or more if you have space. Minimum spacing would be just over 3 feet.
