Hi Gary,

In my opinion they are a pain!  I entertained the thought 35 years 
ago, and quickly discarded it!!

I use thin wall pvc large enough to accommodate the "N" fittings that 
I use on ALL my antennas.

I use a piece long enough to go thru the wall,  angled a few degrees 
down to keep out drip water, and project an inch inside and about two 
inches outside...Now if I want to change the coax going thru a 
particular hole, I simply slide it out and insert the 
replacement...Takes minutes, no additional connectors, no additional 
loss other than a short drip loop, costs pennies...and I use them for 
other cables to the outside...

I now have20 holes in my wall to the outside, I can move gear around 
at will....I plug the holes here with a small piece of cloth to keep 
out the moisture and the bugs....15 holes or so always have a length 
of coax going thru it, sometimes more!!  Yes, I have a farm (antenna)...

I know about where you live, and you may need a plug of insulation in 
the winter!!
