I wouldn't expect much performance from a Beverage built like that. A
bi-directional Beverage will have a lot more noise than an single
direction one, and connecting the ground to the station ground will
allow all the station ground noise to appear in the signal. It could
also destroy the pattern because of the signal picked up on the house
wiring, which also gets into the output.
Build it like everyone else does, separate ground rods at both ends not
connected to anything else, add termination resistor, use transformer
with good primary to secondary isolation or lots of chokes on the feedline.
