IHeartMedia’s ERI 6-Bay LYNX Dual Input FM antenna, which is the top-mounted antenna on the left, combines separate FM analog and HD digital transmitters. At the time it was installed, this was the lowest-loss method for broadcasting hybrid HD Radio signals. The antenna on the right is sister station KOST’s ERI MPX-4E FM antenna. KLLI’s directional 1182-2CP-DA FM antenna is owned by Meruelo Group. Photo courtesy of Doc Searls, see more here.
