[time-nuts] T'bolt antenna lead-in running near HF RF transmitting coax

Can I run the coax feed-in from a Symmetricom 58532A GPS antenna  
(feeding my T'Bolt) adjacent to coax which is carrying HF RF of 500  
watts?  I have a 1.5"  hole through an outside wall in my house  
through which my HF ham antenna coax passes (LMR400 coax).  Can I  
safely run the GPS antenna coax through the same hole which would put  
the coax parallel with and touching the other coax for about 8  
inches.  If not, how much separation would be advisable?  Many  
thanks.  Jim Robbins N1JR
