If the attic area is not large enough to accommodate an almost full size dipole simply erect as much of the antenna as possible in a straight line then bend the ends of the dipole up down or sideways from the main portion of the system.

Attic folded dipole. The infamous attic dipole. Attics are great locations for indoor antennas. Bend the wires as much as necessary to make the dipole fit into the available space. We start with bending the endsof an ordinary center fed dipole limited by an attic garden wall etc.

I was advised. Then folding the endsback part way or into triangles. It is possible to test tune the antenna by folding the ends of the legs back on themselves but in my case the antenna was built using copper weld wire and aircraft anstad type insulators which are apparently quite a pain in the butt to work with. The better your antenna the more success you will have making contacts.

For a platform without rules and restrictions check out this upcoming goodness. You should attempt to maintain symmetry in the system by bending the ends of the antenna in equal amounts. The 40 meter dipole was loaded with some coils so that i could fit it in the attic. Posted on 2015 12 24 by james.

It gave me 40 20 and 15 with a push because although a 40 meter dipole should give you a resonant 15 meter antenna in this case with the coils for 40 it mucked the maths up and caused the atu some trouble. This was installed at a previous qth i will be the first or millionth remember i m from fl to affirm that the antenna is the determining factor for success when it comes to one s station set up. To form v or l typeconfigurations. For example you can install a wire dipole in almost any attic space.

Upand down side to side. On 40m it worked a treat. Or to reduce turning radius. We then look at bendinga dipole in the middle.
