Maco beams work good and are pretty easy
to setup.

Are you going vertical or horizontal? If you are going horizontal, why not add one more element and optimize the beam to the new dimensions using the Maco M104C:

If you want to go vertical, there are a lot of other things to take into consideration. Tuning will NOT be the same! Most people think you can just flip it to vertical, but that is not true.

You should try and get it up at least 10' above the rooof if possible, that is if the roof is "composition", if it is metal, then that's not going to work very good for you.

Horizontal yagi's don't like them metal roof's very well.

A horizontal antenna will be useless for local communications. It will work, but you will have 20db of isolation from the stations running vertical. Also, the distance this antenna is above ground will change your take off angle. If it is too low, you will not be a happy camper.

Take heed to the comments about the metal roofs! They are right!

My personal opinion, setting up this antenna the way you have described is a total waste of your time and money.

i dont have a metal roof so that is good. i have some extra pipe, enough to go up to 60' so i will probably do that. i have to beef up the base i guess to support all the new weight. i live in a rent house so i was thinking about getting a 55 gallon drum from work and filling it up w/ concrete and using it as a base for the mast. i also have a bracket that is attached to the house about 10' up. so, if i have enough height should i go horizontal or vertical for best dx'ing? i probably wont be using the beam local unless i have to.

Horizontal my good man. If you had a beam that went back and forth between horizontal and vertical, like the Moonraker IV, you would see that some times there is an advantage of one over another.

BUT!

If you only have the one option, always go horizontal for DX.

Don't waste your time with the 55 gallon drum. Sink a foot or two into the ground to stop the bottom of the mast from moving and bracket it to the side of the house. Use a rafter beam coming from inside the house to secure the mast to! Most people think the facia board is secured good enough. This is NOT true! Only a couple of nails hold those in place! I would even go as far as to support the rafter you tie off to, INSIDE the roof of the house.

If you go 60', make sure you use guy wires to support the pole.
