Homebrew Beam for 11 meter (27.3850)

[8113 Northern MN]

Anyone have some good step by step instructions for building a good beam for 11 meter. I currently am running a Imax 2000 on top of a telescoping tripod tower. My plan is to build a beam and mount it horizontally underneath the Imax into a switch box so I can switch back and forth between the two.

So looking for anyone who might have a good plan for one laying around. Any help is greatly appreciated!

There is this http://www.csgnetwork.com/antennae3ycalc.html as well as this http://www.skyscan.ca/3ElementYagi.htm along with many other sites.

Moxon rectangle. If you can nail bits of wood together in a H or X shape you can build a Moxon.

Many plans for 11 meter moxons as well as 11 meter yagis on line.

OR go to cb tricks site and look at the many yagi instructions there in antenna section.

The instructions are for a 10 meter Moxon but he formulas are there so all you have to do is plug in the 11mtr frequency to the formulas to get the correct dimensions http://www.dxzone.com/cgi-bin/dir/jump2.cgi?ID=9325

How to make a 2 element yagi. Boom length a little over 7.56' as the two elements-reflector and driven element- are 7.56' apart, giving you an impedance of 50 ohms. Driven element length 17.2' broken in the middle and insulated from boom. Reflector 18.06' need not be insulated from boom. Wind ugly balun and mount on boom and insulated from boom. Directions for ugly balun all over internet and for 11 meters consists of about 8' of coax wound on 2" pvc pipe. Hook coax to balun and other end of balun to the driven element. Gives a little over 4 db gain, better than a hex beam but not as good as a quad. Used one of these for many years on 20 meters. Good luck, wb0snf

2 Element Yagi

Was wondering if anyone has dimensions for a 2 element yagi on 11 meters. Space limits a 3 element or higher. I have the Maco BA1 dipole, thinking of adding another element and make it a 2. Having a hard time finding any info for a 2 element yagi for 11 meters. Any ideas or info.Thanks

Look up Mower Junkie on YouTube, he has a lot of homebrew beam Ideas and shows how to build them. That's where I got the plans for my homebrew antenna

The original poster hasn't been on here for several years 2016 I think it was.
I guess the topic is still relevant.
