Equipment / Re: Sometimes a blob is better.
« on: May 12, 2022, 2122 UTC »
An antenna arm that is half WL (wavelength) long has a pattern with only 2 lobes.

A 1 WL long arm has a pattern with 4 lobes.
A 1 and half WL long arm has a pattern with 6 lobes
A 2 WL long arm has a pattern with 8 lobes
and so on, add 2 lobes for each half wave added to the arm length.

As the wire becomes longer and longer, the stronger lobe is closer and closer to the wire.
Knowing this pattern is the key to design long V antennas and rhombic antennas, so that the main lobes of all the wires add together in the axis, and the other lobes more or less destroy one each other. The apex angle of the V or the rhombic is chosen to get the best combination of the main lobes (to some elevation angle).

If you use only a straight long wire, you will get a pattern like a daisy flower !

So, usually there is no reason to use center fed antennas longer than 1 WL (apart convenience for multiband use, or well chosen different directions). For better results to long distances, the right way is to place the antenna as high as possible, giving better efficiency, and better low angle gain.

Beware! For simple HF antennas, gain is a misleading idea. More important is the efficiency (also in receiving, as a receiving antenna is also radiating), and about that, many simple antennas are far in the negative range of effective gain. More, for receiving, that effective gain is only next to the noise pickup, the right idea being to get the best S/N ratio rather than the highest S level.
