[grc] Calculating TPO

[Michelle Bradley]

55w ERP for 100' of LMR-400 into an antenna with a -3.37 dB of loss, I 
get 160 watts TPO.



TPO in watts_____________________: 	160 	watts 	.
TPO in dBm_______________________: 	52.0412 	
	(10*LOG10((watts * 1000)/1)).
Line loss and equipment__________: 	1.238089 	
	.
Antenna gain in dBd______________: 	-3.37 	
	In reference to a dipole.
ERP dBm__________________________: 	47.43311 	
	(TPO in dBm-line loss+antenna gain).
ERP in watts_____________________: 	55.37466 	
	(10^([ERP in dBM]/10)/1000).
