Topband: Daisey Chained ground rods

      It seems to me what your asking here is how much
 crosstalk you would see between two Beverage
 antennas. How about just using a signal source and
 exciting one beverage while listening on the other.
 This could be a most enlightening measurement not only
 for the ground rods but for the placement of the antennas
 themselves. An MFJ 259 generates quite a signal and
 could be used to excite an antenna while listening to the
 other. One could also feed the MFJ 259 directly into the
 receiver first to get a reference level. Be sure and check
 that the MFJ259 does not put out too large a signal and
 could damage your RX first! The ratio of the two levels
 would indicate the crosstalk whether it is from the ground
 posts or antennas.
     Aren't they both just as bad?
