Nowadays one of the specialized and important issues in construction of marine floats is to design the communication telecom system between them. Always this issue has been posed how to establish an appropriate communication for floats in different distances and different weather conditions in the sea. Due to the restrictions, such as equipment size, weight bearing on the floats has always existed.One of the main parts of telecom communication system is antenna.The main problem, use antennas and Towers various in floats, As required, waves with different wavelength sand different routes to be published. If the antenna can be designed with small dimensions and possible,wide frequency range and also covered omni-directions, the problem has been mentioned above somewhat is resolved. The purpose of this paper is to design and simulate of a sample of integration broadband antenna and omni-directional, that resolve About restrictions above and Integration of two antennas in frequency range of VHF/UHF=150-450MHZ and HF=3-30MHZ with characteristics of 50ohm input impedance, linear vertical polarization, VSWR<2.5, antenna gain ranges between (-12)dBi to (4.8)dBi, the maximum antenna diameter of 18cm, and the maximum height of opened antenna of 538.2cm.
