Welding Leg Flanges to a New LAMBDA® Optimized FM Mounting System

Welding flanges onto the legs of a new ERI LAMBDA® Optimized FM Mounting System. The LAMBDA® mounting system was designed initially to reduce FM antenna failures due to stresses from tower movement.  The design specified a maximum bending radius of the top-mounted free-standing tower sections, and this resulted in a very stiff tower designed to support side-mounted FM antennas. Typical 20-foot tower sections do not allow symmetrical antenna element mounting locations because the cross members will have a different geometry behind each of the array elements. LAMBDA tower sections make the signal scattering from the tower a constant because the structural member spacing is a halfwave at the operating FM frequency.  All the antenna array elements see the same tower face geometry because the tower’s reflected (scattered) signal is identical for each bay of the array.

WXXI-TV Rochester, New York – Top Mounted UHF TRASAR® Television Antenna

The antenna pictured is the new ERI TRASAR® elliptically polarized UHF television installed for WXXI-TV’s new repack RF Channel 22 antenna. The move from RF Channel 16 to RF Channel 200 was part of the FCC mandated repack to free up RF spectrum for wireless communications. The antenna is mounted at the top of the 276-foot WXXI owned tower on Pinnacle Hill southeast of Rochester. The top of the TRASAR antenna is 345-feet above ground level. This antenna replaced the RF Channel 16 elliptically polarized ERI TRASAR antenna installed in 2014. Photo courtesy of Mike Fitzpatrick/
