Un rol important in domeniul comunicatiilor VHF il au repetoarele de semnal. Aceste dispozitive permit
realizarea unor comunicatii la distante mari caracterizate de un raport semnal/zgomot mare. In aceasta lucrare mi-am propus sa realizez o antena verticala “omega”pentru banda de 2 m care sa fie utilizata in componenta unui
repetor digital. Am testat performantele acesteia, cunoscut fiind faptul ca o antena cu un castig ridicat are avantajul sensibilitatii pentru semnalele provenite de la transceiverele portabile sau mobile de putere mica.

Abstract
An important role in VHF communications, it have signal repeaters. These devices allow for long distance
communications, characterized by a high signal / noise. In this paper I wanted to achieve a vertical antenna "Omega"
for the band of 2 m, which is used in the composition of a repeater. I tested its performance, knowing that a high
gain antenna has the advantage of sensitivity to signals from mobile or portable transceiver for low power
