The Lazy Inverted-L (or Lazy Inverted-V) Antenna
For installations where we do not have a second elevated support for supporting the far end of the Inv-L antenna, we can make it LAZY. We do this by sloping the horizontal segment of wire towards the ground.
The advantage is, we don't need a second elevated support. However, the frequency of minimum SWR on each band may shift slightly and the bandwidth is slightly less than when the horizontal leg is strung horizontally.
This is basically an Inverted-L antenna with a sloping horizontal leg. Perhaps Lazy Inv-V is a better name. Whatever!
We run part of the antenna vertically up a non-metallic pole (i.e., fiberglass pole) and we run the rest of the wire diagonally back towards the ground.
Although the drawing shows two diagonal wire, we only use one wire. The
green wire (45 deg.) shows the minimum angle we should use. The
blue wire (60 deg.) will be a better performer if you can hang it this high. Of course you may hang it any angle in between, or even higher than 60 degrees.
Like the vertical antenna and the Inv-L antenna, this "Lazy Inv-L" (or "Lazy Inv-V") requires a good radial network beneath the radiator in order to have good performance. For information on radial networks, see RADIALS.
