Thanks Phil,  Yes, I was planning 120 degree angles for anchor placement
but am more concerned about down angle.  I had not thought about house
brackets but could do this but would rather not.  I suspect concrete
will be the choice.

Brett,

It depends on yard size, first of all.  Even a smaller yard will work
based upon where the tower is located on the property.  I've had guyed
towers bolted to the back of my house at the 14 foot level with one set
of guys on a 40 foot tower and a 4 element 20 meter beam on a 26 foot
boom.  I have a 50 foot free standing tower now bolted to the house at
12 feet and no guys but just use it just for small 2 meter antennas and
wire antennas.  Climbing it to the top is a little nerve racking but I'm
getting old, too.  120 degree spacing between the three guys is
recommend by Rohn, or used to be, and the angle can be shallow but not
too shallow.  I had 4 inch I D 10 foot long guy anchors about 5 feet
into the ground with concrete.  Way less than a yard is good enough
based upon how big of antenna you are going to use.
My friend with the 132 foot tower had 12 foot guy anchors because his
yard wasn't large enough for guys clear to the ground.  My yard was too
small for my 65 foot tower so I used the above ground guy anchors to
make up the less than perfect down stroke angle and less than 120 degree
separation between guy levels and cables.  There are guys on here who
know a whole lot more about towers than me, though.

Phil.
