AGL  Above Ground Level.  Height above common ground to the midpoint of the radiating antenna.

• Miscellaneous losses are caused by ground reflection, atmospheric absorbtion, interference, or whatever.
• Assumes 0.25 dB loss for each coax connector or adapter.
• Attenuation of a 2.4 GHz signal in heavy rain (150 mm/hr) is 0.02 dB/km.
• Attenuation from trees is approximately 0.35 dB/meter at 2.4 GHz.
