Topband: safely sharing an RX antenna

[Bob Kupps via Topband <topband@contesting.com>]

Hi I was thinking about using a 3dB splitter and tuning the band with our 
second K3 using our HiZ monoband 8 circle while we were calling CQ in the Stew. 
The center of the array is located 105 meters from the xmit vertical, uses 20' 
elements, the included preamp and 100m of RG6 transmission line. 
Could dangerously high signal levels appear at the unmuted second radio antenna 
terminal? What about if the second radio is inadvertently tuned to the xmit 
frequency? It would seem impossible if the external antenna preamps are not 
damaged...but I'm still a 1R op so I better ask first!
