Subject: RE: Tesla Digest, Vol 142, Issue 1 RF Police Tx power: Try this link: https://www.pasternack.com/t-calculator-ratio-conv.aspx Your 10,000 VA coil puts out +70 dBm signal Signal loss: Try this link: https://www.pasternack.com/t-calculator-fspl.aspx Pasternack calculator will tell you the signal loss for your resonating frequency and distance to someone who may have a concern. If 100 kHz transmits 1 mile away, you only lose 16.57 dB. Your signal will still be quite strong. If 1 MHz transmits 1 mile away, you lose 36.57 dB... so more loss the higher the frequency, which means less interference at higher frequencies.
