[NCC] Through Wall suggestions

[Jim Breakall]

Hi Tim,

In the professional communications world into shelter buildings, etc. 
and what we did at the K3CR contest station,
you can use rubber boot assemblies for the heliax cables made just for 
this purpose.  We tried the PVC pipe approach
also with steel wool in it but the mice would eventually pull out the 
steel wool and still get in.  These rubber boots
seem to be more full-proof and they don't seem to like to chew on the 
rubber.

Good luck and the main thing is to keep mice and hornets out of the 
building.  We eventually put all of the heliax and lightning arrestors and
antenna switches in a large container shelter outside and then just ran 
very few cables into the building.
