I believe it is ON4UN's book where there was discussion of inside vs 
outside. If you wanted to shunt feed the tower then inside was preferable as 
I recall. Apparently minimizes RF on the feedlines.

Subject: [TowerTalk] Feedlines: inside or out on tower?

After reading John's (KK9A, P40A) post regarding tower painting, I have a 
question for the group. While I would be hard pressed to recall a tower I 
have worked on that has not had its feedlines and control cables run on the 
inside of leg, it is obvious from his post that not everyone does so. What 
is the thinking behind running the cables on the inside or the outside? BTW, 
I've even seen hardline run on the inside of 45 and 55, glad it wasn't me 
who had to install it.
