Which one 96.6 + 20logD + 20log F Where F D are GHz and Miles. or 20logD + 20log F + 32.44 -Gt -Gr = FSPL where t is tx pwr and r is receiver sensitivity. Jaime Solorza Wireless Systems Architect 915-861-1390
Re: [AFMUG] Free Space Loss calculator
Well do you want to use miles and GHz or meters or feet KHz or or or? This formula may be for meters and cycles per second. That is what the constant does, the 32.44 it adjusts for units. Then the Gt and Gr are the gains of the antennas I presume.

Re: [AFMUG] Free Space Loss calculator
Yep, I think this is the formula for meters and MHz: FSL = 32.5 + 20 log F + 20 Log D Where: D = Km F = MHz If Gt and Gr were gains, they would be additive – not subtracted, so I’m unclear as to what these actually stand for.

Re: [AFMUG] Free Space Loss calculator
i want to sleep.i was asked about my calculations and they sent me that formula. I had seen it before but I use the one you do for quick stuff and use RM or other calculators with more bells and whistles to do actual.
