This useful model can be used as simple transmitting and receiving antenna in wideband communication systems.

Serial production of wideband antennas for HF and VHF transmitters is realized. During antennas manufacture useful model protected by certificate №19611 was used. In proposed unbalanced vibrator operating frequencies widening is realized by means of ferrite rings. Technical documentation for antennas is developed which operate in frequency range 2÷300 МHz. In operating frequency band not less than octave voltage wave standing ratio does not exceed 3. For each frequency sub band ferrite rings features are selected, their number and installation place in vibrator. The advantages of antennas with ferrite rings are simple for manufacturing and tuning. Their parameters are stable in wide operating temperature range.
