I have a 2 inch mast stuck in the ground which I use for antenna assembly. (A piece of old TV mast tubing 2" in diameter is used as the "drill" to pull out the dirt, several inches at a time, then in
I've assembled a lot of yagis, but always seem to run into the problem of getting the elements to line up with each other in a horizontal plane parallel with the ground. I'm about to assemble several
Larry, Don't worry too much about it. The "alignment" is for your eyes only. The elements may be off horizontal alignment by as much as 30 degrees, or more, before it will affect anything related to
Hi, Larry. I bought an eight foot bubble level from Sears. First I carefully plumb the mast and then one of the elements. From that point, I simply eye-ball the remeining elements to the plumbed one.
of Larry, Your eyeball is better than you, or most of us give it credit for. The little secret I learned from my Elmer (my dad) was to not try to assemble antennas on the ground, or milk crates, or

Bill: I sort of wish you hadn't given away the secret. It is much more fun to read about all the agony people go through to get alignment of elements. only. The degrees, or more, Maybe the thing to d
Before this goes the route of True North, polishing elements, etc., let me clarify that the intent of the question was never to get better RF performance. I'm after asthetics... neighbors are patient

I use a large construction square (the L shaped thing) and a long level. Set the edge of the square on an element and the other edge lines up with the level. Check both sides of el. relative to boom.
<< Any tricks of the trade out there for getting this right the first time? >> 1. Place the boom on a couple of saw-horses. Attach a piece of mast to the boom-to-mast bracket and secure. Make it long

Kurt wrote to Larry: Kurt's response is the correct one, Larry. Once you have the boom levelled and trussed on the temporary mast, the rest is easy. Bonus: When you get it up on the tower later, all
