Construction |
- 2 x 12m mast (or suitable supports)
- ¼ λ antenna element with as much in the vertical as possible, remainder bent over the top
|
Use |
Static, HF net working |
Range |
0-100Km |
Polarity |
Vertical |
Radiation Pattern |
Omnidirectional with slight gain towards the bend |
Propagation |
Surface wave with a little skywave from the horizontal part |
Advantages |
More efficient than a rod or wire of the same height |
Disadvantages |
- Takes a long time to set up and take down
- Can receive skywave signals
- Fading is caused at certain frequencies when the surface wave and skywave signals arrive out of phase with eachother
|
Remarks |
Particularly useful when using surface wave at lower than 4Mhz when it is important to keep the antenna as vertical as possible |
