Buddipole antenna full#

The 20m band is an even harmonic of 40m which is a particularly bad case (that creates a full wave dipole on 20m). This is not the fault of the ATU but because of high SWR in the coax.Ī classic example of this is to set an antenna up for 40m and then use a tuner to operate on the 20m band. The bottom line is that using an ATU to use an antenna setup for a band that is that is not close to resonance or an odd harmonic is likely to return disappointing results. That loss occurs within the coax so is typically invisible to you. In that case the low SWR at the radio is not a good indicator of efficient power transfer.

Even if you have a tuner that can deal with the massive mismatch resulting from driving an antenna on a band that it is not tuned for, that massive mismatch can result in serious SWR induced cable loss. transceivers with power handling up to 250W PEP. as a tabletop, tripod or mast mounted vertical. a new feed point design called the 'Versahub', which provides the ability to configure the antenna.

That is particularly true when the antenna tuner is located at the radio end of the coax (the most common configuration). The BUDDISTICK PRO HF vertical antenna is based on. The use of an ATU to tweak up an antenna that is already tuned fairly close to resonance works very well, but using it to tune an antenna on a completely different band is problematic.

However the 6m band is not an exact half multiple of 40m so it is unlikely to resonate - and anyway you can easily create a full size half wave 6m dipole that works really well. Other than that I would guess you need to 'just try it' and experience yourself.Yes a dipole will be resonant not only at the half wave length, but also odd multiples above that so if you have a 40m antenna that includes the 15m band. Saying that, I was not looking or executing any measurements either, so if there was a difference then I probably would not have noticed it. I have done it, I cannot recall any difference vs the normal dipole config. And while you have the feedpoint higher, you may as well run a half-wave (two quarter wave) wires, to have a normal inverted V. This would be speculative, but in my opinion if you need an inverted V, you need to get the feedpoint up higher than traditionally done with the Buddipole.

Buddipole antenna manual#

Because of these factors it is recommended that the user refer to the Buddipole antenna manual as a starting point for tuning the Buddipole in these different configurations, with a realization that some tweaking may be necessary to achieve a good match. Why is this not a more popular configuration? the antennas orientation with respect to the earth.As the Buddipole itself is a compromise antenna, there are many design factors to take into account, which makes the math on detail even more complex.Ĭhances are that some detail is indeed overlooked, simplisticly speaking.

Buddipole antenna portable#

This antenna is portable and small enough to use camping. I believe that in order to answer that you need to experiment, measure, and probably apply complex math's to answer such a question. In this Gadget Talk video well take a quick look at a portable HF antenna for ham radio operators. However to say that 'no one' uses this, is probably an overstretch While never really experimented or measured it, I am not sure about either advandtages or disadvantages of such. I cannot recall if the results were any different then the elements horizontal. However I must say that I have experience with the Buddipole. 'no one' probably is an assumption which is speculative. Why does no one use a Buddipole as an Inverted V?.

Reason is probably that questions 1/3/4 are quite speculative. There are good answers given for question 2, but not for the others. Why is this not a more popular configuration? I think it would also bring the impedance closer to 50 ohms which would eliminate the balun requirement, right? Please select from the drop down menu whether you would prefer any of the SO-239 connectors with the cable. Operating hours: Monday - Friday 8am - 4pm PST. They can also be used with our Triple Ratio Switch Balun (TRSB), or for any other antenna system. Why does no one use a Buddipole as an Inverted V? These cables can be used with our choke balun that comes with the standard Buddipole. There are 4 questions in the original post:
