OUT-AWAY-AND ABOVE :

Out from the House or Building by 15-25 Feet or more away from
the House's RFI/EMF Fields and Man Made Noise.

Away from any exterior sources of RFI/EMF by 15-25 Feet or more.
- Other Buildings, Lighting and Power Lines.

Above the Roof and Up and Away from the House's RFI/EMF Fields
and Man Made Noise by 15-25 Feet or more.

Any combination of : 15 to 25 Feet Out, Away and Above will work.

10 Feet Out and 15 Feet Up is 25 Feet Away

15 Feet Out and 10 Feet Up is 25 Feet Away

One Foot Out and 14 Feet Up is 15 Feet Away

Three Feet Out and 21 Feet Up is 24 Feet Away

30 Feet Out and 5 Feet Up is 35 Feet Away

25 Feet Out and 25 Feet Up is 50 Feet Away

TIP - With the Coax Cable Feed-in-Line Attached.
Use a 50 100 Foot piece of Nylon-Poly Rope and
starting in the 1/3 the Length of the Rope. Tie a
Clove Hitch at the Base; with a Clove Hitch in the
Middle; and a Clove Hitch at the Top of the Active
Antenna Element. Leaving 1/3 of the Rope at the
Bottom and 2/3 of the Rope at the Tope. Rig the
Rope over a Tree Limb so that the Vertical Antenna
is about 3-5 Feet from the Limb and the Rope Falls
directly to the Ground with a Stake in the Ground to
Secure the Bottom Ends of the Rope.

hope this helps - iane ~ RHF
