Because of its central location and relatively high altitude for central Iowa, two Doppler weather radar stations are located in Alleman: WHO-TV 13's First Alert Mega Doppler, and KCCI-TV 8's Super Doppler 8. A storm in July 2011 resulted in the radome from the Mega Doppler being torn from the structure and landing in a nearby yard.
Because Alleman is located about midway between Des Moines and Ames, many radio and television stations transmit from towers located in the town. These towers include some of the world's tallest structures, reaching over 600 meters. Along with the towers, a large portion of the Alleman low-altitude airspace is obstructed by the many guy-wires supporting the structures, making the area extremely hazardous for small, low-altitude aircraft. The specific antennas are:
- Local TV Iowa Tower Alleman, 609.6 m (2,000 ft), constructed in 1972.
- Des Moines Hearst-Argyle Television Tower Alleman, 609.6 m (2,000 ft), constructed in 1974.
- Saga Communications Tower Alleman, 469.1 m (1,539 ft), constructed in 1982.
- American Towers Tower Alleman, 609.3 m (1,999 ft), constructed in 2001.
