Is a longer antenna better?
So the answer is yes, size does matter, but bigger isn’t always better. It all depends on what your transmitting and receiving frequencies are. Theoretically, a longer antenna will have a greater range, but it is far more important for optimal radio performance that the length of the antenna matches the frequency.
What is effective antenna length?
In telecommunication, the effective height, or effective length, of an antenna is the height of the antenna’s center of radiation above the ground. It is defined as the ratio of the induced voltage to the incident field .
What is the length of antenna?
Antenna lengths for popular ham radio bands
| Approximate Lengths for Ham Band Dipole Antennas | ||
|---|---|---|
| Band (MHz) | Length (feet) | Length (metres) |
| 3.5 | 137 | 42.2 |
| 7.0 | 68.5 | 21.1 |
| 10.1 | 47.5 | 14.7 |
Does bigger antenna mean better reception?
A bigger antenna, properly designed, will always have more gain than a smaller one. And it will be the best kind of gain, much better than using a small antenna and simply overamplifying it, because a small antenna just won’t pull in truly weak signals like this gigantic one will.
How do you measure antenna length?
Basic calculation is the speed of light divided by the frequency. Say of an airband antenna to receive 125 MHz then it is 300/125 = 2.4 meters full wave length. Commonly, but not exclusively, antennas are either a ½ wave dipole hence 1.2 meters or a ¼ wave monopole hence 60cm in length.
