Topband: FT-920 RX-Antenna and Beverages

[Magnus A]

Hello!

Can anyone tell me if they had a positive result in using a FT-920, it's 
RX-antenna jack and beverages?
It seems that some rigs is not well equiped with the RX-Antenna usage and 
that in some rigs the RX-Ant dont ground while TXing which may cause RF 
coming in and damaging the front end if the beverage picks up to much RF 
from the TX-antenna.
