Which UHF TV services does the ARL451212.1WZ cover?

The ARL451212.1WZ is designed for the UHF TV band 470-860 MHz and is suitable for DVB-T, DVB-T2 and DVB-H broadcast infrastructures, as well as professional UHF distribution and monitoring chains operating in the same spectrum window.

What are the advantages of a log-periodic (logarithmic) antenna in the 470-860 MHz band?

A log-periodic antenna provides stable broadband behaviour across the band, controlled beamwidth, good front-to-back ratio and clean radiation patterns, which are valuable in professional UHF broadcast sites and engineered coverage plans.

Can I use vertical or horizontal polarization?

Yes. The antenna supports V/H polarization, allowing alignment with the required broadcast network configuration and site engineering requirements.
