The length of your radials is a function of the number of them. The ARRL Antenna Book has a lot of very good information about this. 73, Larry W1DYJ _______________________________________________ __

My understanding is that the linear distance between radials determines ground resistance which needs to be minimized.. This is why more radials continue to be useful when they are longer. The shorte

Hi Tony, 3 dB is a doubling of power. Therefore, if a transceiver had a true reading S-meter, it would take an increase of from 100 w. to 400 w. to see an S-meter increase of from, say S5 to S6. 73,
