SUTRO Tower
San Francisco’s SUTRO Tower is home to UHF Broadcast TV Antennas and many other Communication Antennas. In 2016 the Federal Communications Commission (FCC) began an “incentive auction” that effectively required that all UHF TV channel move down below 600 MHz (UHF Spectrum Repack). San Francisco was one of the twenty-six locations nationwide that had one of its stations reassigned to channel 14.
Land Mobile Radio (LMR) operate at frequencies below UHF TV with the highest band operating at 460 - 470 MHz which is adjacent to Channel 14 (470-476 MHz). Broadcast TV transmitters outputs are significantly higher power levels than LMR, so the new Channel 14 transmitter would pose a significant interference risk to LMR’s operation at the tower.
S. Merrill Weiss (Merrill Weiss Group LLC) reached out to MFC with a design outline to create a RF Filter solution that would prevent interference to LMR receiver collocated on SUTRO Tower. MFC’s team of design specialists, along with Merrill and his folks, worked remotely to create the perfect solution. Deployed in 2021, the filter is mitigating interference successfully.
