WebThat "formula" for a half wave dipole, as we all should have learned here in the U.S., is based on a ... so you plug in the formula into your calculator and get started. 468 / freq in Mhz = total length in feet for a half wave dipole. You want to center your dipole on, as an example, of 14.300Mhz. So, using the formula 468/14.3...we get 32.72 ... WebThe directive gain of a half-wave dipole is known to be 1.64 and it can be made nearly 100% efficient. Since the gain has been measured with respect to this reference antenna, the difference in the gain of the test antenna is often compared to that of the dipole. The “gain relative to a dipole” is thus often quoted and is denoted using ...

WebThe W3EDP antenna works well on 80m and 40m and gives a similar performance to a dipole on 20m. On the bands above 20m it will work, but the performance may be down on what you could expect from a half-wave dipole cut for each particular band. If you do get RF problems in the shack make sure you have a good earth (see earlier). WebCalculate a Dipole. The half-wave dipole is very simple to construct. Use 75 or 50 ohm cable to feed the centre of the dipole. This could be 50 ohm types such as RG58, RG8X, RG8, RG213, or 75 ohm type such as RG11, RG59, RG6 or even 75 ohm twin lead. … WebDipole calculator, HF Wire Dipole Antenna Calculator for Amateur Radio / Ham Radio / CB Bands.
