Model 513

Innovative Antenna Design for Exceptional Performance

The Model 513 Di-Monopole® Hybrid Log offers a groundbreaking solution that combines the best features of vertical dipole and monopole log-periodic antennas. Engineered to deliver superior performance and practical usability, it is an ideal choice for applications requiring high gain, substantial power handling, and minimized structural impact.

Vertical Dipole Advantages Without the Trade-offs
Traditional vertical dipole log-periodic antennas are known for their high gain and power-handling capabilities. However, their reliance on large tower heights—often exceeding half a wavelength at the lowest operating frequency—poses significant challenges in extreme environments and areas near airports. The Model 513 overcomes these limitations by reducing vertical height requirements without sacrificing performance.

The Best of Monopole Technology
Monopole log-periodic antennas are valued for their reduced vertical dimensions, making them structurally advantageous and operationally feasible in areas with height restrictions, such as near airports. The Model 513 incorporates these benefits while addressing the common shortcomings of monopole designs, such as reduced gain and the need for expensive, complex ground screens for impedance matching.

Hybrid Design for Optimal Performance
The Model 513 Di-Monopole® Hybrid Log blends the strengths of both technologies, offering reduced structural height for easier installation and operation, without the costly requirement of a ground screen. This innovative design ensures high gain, excellent power handling, and adaptability across a wide frequency range, making it a versatile and efficient choice for diverse applications.

Built for Challenging Environments
Engineered to withstand severe environmental conditions, this antenna is the perfect solution for operations near airports, in constrained spaces, or in challenging terrains where conventional designs fall short.
