Limited talk range

Steel and/or concrete structures, heavy foliage, buildings or vehicles decrease 
range. Check for clear line of sight to improve transmission. 
Wearing radio close to body such as in a pocket or on a belt decreases range. 
Change location of radio. To increase range and coverage, you can reduce 
obstructions or increase power. UHF radios provides greater coverage in 
industrial and commercial buildings. Increasing power provides greater signal 
range and increased penetration through obstructions.
