Romeo" ("R" stands for received). Note: some radio operators use the

d. Antenna height and range of communications are intimately related. In
general, a higher antenna will have a longer range than a similar lower
antenna.
The typical range for a transmitting radio held at about 1.2 meters (4.0 ft)
above average water level is expected to equal 4.5 kilometers (2.8 statute
miles). The receiving shipborne antenna can extend the range if it is mounted
high. Airborne receivers greatly extend the above range (over 150
kilometers/100 miles for aircraft flying over 1500 meters/5000 ft).
