Did you know?
WebDistance Between Two HF Vertical Antennas The simple answer to this intriguing question is that for a minimum frequency antenna you need to maintain a distance of at least 1/4 of the wavelength, which must be kept to a minimum. In the case of VHF antennas, this distance is 19 inches. Web21 aug. 2024 · A dipole antenna bandwidth should generally range from Δf = 0 (no difference between low and high frequencies) to λ/20 (a 20% change). A good rule of …
Web15 okt. 2024 · Each wire, or element, is a quarter wavelength of the frequency you want to transmit on. The basic formula for dipole construction is dividing 468 by the desired resonant frequency, in MHz. As an example, a dipole cut for 14.225 MHz SSB is 468/14.225 = 32.9 feet total length. Divide 32.9 in half, and we see each element of this dipole needs to ... http://www.redwaveradio.com/9_1d3bb1f3da443de9_1.htm
Web4 mei 2024 · So for the most part one antenna placed on top of another isn’t going to interfere much. However, I do tend to give people a suggestion and it’s always worked out for me: The space should be the height of the antenna. That’s what I tend to tell people. If the antenna is 2 feet tall, put a 2-foot gap between the two antennas. WebYour first antenna – the half-wave dipole. Many hams’ first choice of antenna is a half-wave dipole. But don’t be misled – just because they are easy to make doesn’t mean they don’t work well. In fact, a half-wave dipole will often outperform many compromise commercial multiband antennas.
Web18 jul. 2002 · antenna separations. In general, you want to keep them as far apart as possible, or within reason. Usually a 1/4 wave separation is the 'rule of thumb'. With 6 and 2 meter antennas, I'd use at least a 1/4 wave or about 2 feet separation, more is better. A 1/4 wave at the higher frequency of the two, sort of.
