ARTICLES

Tagliabue, C., "How to calculate large capacitive and inductive devices", 2021 <http://www.i5tgc.it/capinden.htm>
immagineThe article summarizes the considerations and the series of calculations that the author had to carry out to realize capacitive and inductive elements of considerable size used in his antennas. The expressions used in the calculations are the classic ones, supplemented by some written on the basis of his experience on the subject.
Tagliabue, C., "Correttore e limitatore di B.F.", in RadioRivista, n. 5(1978), pp. 447-450
The article describes a device that operates in BF and can be connected directly to the 'headphone' output of a receiver, returning a signal sufficient to drive headphones with even relatively low impedance.

Tagliabue, C., "Alimentatore 25 A", in RadioRivista, n. 3(1983), pp. 83-89
The article describes a power supply, adjustable in voltage and current, designed to meet the specific needs of radio amateurs. Mario Cappelli i5WBJ contributed to the realization of this device.

Tagliabue, C., "Il nostro oscillofono", in RadioRivista, n. 6(1983), pp. 92-93
The article describes a circuit created with particular characteristics in view of its use for the collective learning of telegraphy.

Tagliabue, C., "Rettangolo da soffitta per HF", in RadioRivista, n. 3(1984), pp.42-43
The article describes the tests carried out with a very small antenna that could be used, with a fairly modest loss, in cases where it is impossible to install a normal antenna.

Tagliabue, C., "Evoluzione del 'triangolo [sic] da soffitta'", in RadioRivista, n. 2(1985), pp. 33-37
The title of the article contains a typo, since there is still talk of the 'attic rectangle' already discussed in n. 3 (1984), completing the description of the antenna and describing the results achieved (see also Monoband loop for 14 MHz on the HF antennas page).

Tagliabue, C., "Ritorna il 'rettangolo da soffitta'", in RadioRivista, n. 4(1987), pp. 42-47
In this article we return to talk about a small antenna developed especially for its use indoors (see also Monoband loop for 7 MHz in HF antennas). The same issue describes a device for remote tuning, very useful for antennas with limited bandwidth (see also Remote tuning unit in HF antennas).

Ciapetti, C.L., Tagliabue, C. (con la consulenza di), "La riscoperta di un'antenna multibanda", in RadioRivista, n. 7(1987), pp. 36-40
The author Carlo Luigi Ciapetti describes his experiences in the 160 meter band and the characteristics of the Levy multiband antenna.

Tagliabue, C., "Il dipoloop (& C)", in RadioRivista, n. 6(1989), pp. 44-48
We return to the topic of small antennas, clarifying some doubts about their efficiency and specifying again that the use of this type of antenna must be dictated by specific needs, such as lack of space, need to operate indoors, portability. (see also Monoband loop for 7 MHz in HF antennas).

Tagliabue, C., "Antenne di dimensioni ridotte. Nuovi sviluppi", in RadioRivista, n. 2(1991), pp. 26-32
We are talking about small antennas and new experiments in this field (see also Vertical dipole for 7 MHz in HF antennas).

Tagliabue, C., "Una soluzione al problema dello spazio sui 160 metri", in RadioRivista, n. 10(1992), pp. 33-36
The article describes the characteristics of a small vertical antenna capable of operating on 160 meters (see also Vertical dipole for 1.8 MHz in HF antennas).

Tagliabue, C., Furiani, F. (con il contributo di), "Jonoprop.exe, versione 2.1", in RadioRivista, n. 6(1994), pp. 86-88
The JONOPROP program is described, which allows to evaluate the feasibility of radio links via the ionosphere between any two points on the earth and is freely available (see Software). The program has collected very positive evaluations (see Miceli, M., "Le previsioni della propagazione ionosferica", in RadioRivista, n. 3(1994), p. 71).

Tagliabue, C., "Propagazione jonosferica", in RadioRivista, n. 8(1994), pp. 79-82
This issue describes the graphic version (JONOPR22) of the JONOPROP program illustrated in the previous article (see Software).

Tagliabue, C., "Appunti sulla radiazione da antenne semplici - 1a parte", in RadioRivista, n. 5(1996), pp. 19-20
The topic of radiation from simple antennas is treated to demonstrate how it is possible to make antennas of very small dimensions but of unquestionable efficiency. The discussion is divided into five articles; in this first introductory part we recall the principles that regulate the radiation of electromagnetic waves.

Tagliabue, C., "Appunti sulla radiazione da antenne semplici - 2a parte", in RadioRivista, n. 6(1996), pp. 26-27
In this second part of the discussion we talk about the antenna as a generator of electromagnetic waves.

Tagliabue, C., "Appunti sulla radiazione da antenne semplici - 3a parte", in RadioRivista, n. 7(1996), pp. 20-21
The third part deals with the antennas of appreciable dimensions in terms of wavelength and the antenna as a collector of electromagnetic waves.

Tagliabue, C., "Appunti sulla radiazione da antenne semplici - 4a parte", in RadioRivista, n. 8(1996), pp. 35-36
The fourth part concerns the resistance of antennas and the ground effect, often decisive in determining the overall efficiency of an antenna.

Tagliabue, C., "Appunti sulla radiazione da antenne semplici - 5a parte", in RadioRivista, n. 10(1996), pp. 29-33
In the fifth and last part it is about how to reduce the size of an antenna while maintaining an acceptable performance (see also HF antennas).

Tagliabue, C., "Attività sui 137 kHz", in RadioRivista, n. 5(2000), pp. 97-98
This article intends to encourage the activity on the band from 136.7 to 137.8 kHz, remembering that it is possible to operate on this band even if you do not have much space for the antenna, using very short vertical antennas, but which may have an acceptable return; the author then describes his own experience in this regard (see also Activity on 137 kHz).

Tagliabue, C., "Antenna loop per la ricezione dei 137 kHz", in RadioRivista, n. 7/8(2001), pp. 35-36
The characteristics of a loop to be mounted outdoors are described, as mentioned in the article published in n. 5 (2000) (see also LW receiving loop).

Tagliabue, C., "Un transverter originale per i 137 kHz", in RadioRivista, n. 4(2005), pp. 88-89
This article describes a transverter made by the amateur radio colleague I5JRV to push to operate on the 137 kHz band, currently very little frequented by Italian OMs.

RadioRivista is the official magazine of ARI, Associazione Radioamatori Italiani.
