Topband: 1 center point to ground all 8 beverages??

[luc kerkhofs]

Very interesting, reading as always,

This brings me to another question, how do I need to handle grounds in a switch box with 3 antennas ?

 relays to connect only the selected Beverage to the ground

 and disconnect the other seven.
 
 I've done this for 31 years from 3 different locations with
 no problems.

          I agree.  I've
 done this since installing my first set of 7
 Beverages in 1985 arranged like wheel spokes and have never
 noticed
 crosstalk problems.  I even sometimes switched two in
 parallel to
 listen in two directions simultaneously in contests (NE and
 W when I was
 in Colorado).  Now I prefer diversity (Beverages on one
 RX and an RX 4SQ
 on the other RX) for contests.
