Prezentata in fig. 240 a, da un cistig de cimp de. 6—7 GB si are o rezistenta de intrare de 240 Ω. Dimensiunile indicate corespund benzii de 144 MHz.
Antena poate fi realizata pentru orice alta frecventa din gama ultrascurte, inclusiv banda de 432 MHz, folosind urmatoarele formule:
Antena realizata dupa aceste calcule are diametrul tevii din care se confectioneaza,elementele de 12 mm, montata pe o traversa metalica cu diametrul 20 mm.
Daca vom folosi pentru constructia elementelor antenei teava de diametru mai mare sau daca traversa este de lemn, toate elementele antenei vor trebui putin scurtate. In cazul folosirii ca traversa a unei tevi metalice cu diametru mai mare, vom mari putin lungimea elementelor antenei. In fig. 240 b este aratata adaptarea cablului coaxial asimetric cu impedanta de 60 Ω la antena prin bucla de 680 mm lungime (λ/2 corectata cu coeficien-tul de scurtare).
