 Hello:
 
 I was out of town and missed some of the discussions on open wire feeders. I
 have a question that I haven't seen addressed, although it probably has and
 I missed it. I have an 80 Meter Dipole fed with 450 ohm ladder line. At my
 new house, I must run my coax rotor cable, etc. through a 20 foot 3 inch
 conduit to get to the shack. I am thinking that I need to terminate the
 ladder line to a balun designed for such applications and run the coax
 output through the conduit to the antenna tuner to run multi-bands on the
 dipole.
 
 My question is this. I run an Alpha 87A and a 77. What commercially made
 balun would handle that high of power?
 
 Thanks for the info.
 
 73, Mark...

Don't use a balun.  Run the ladder line through a separtae plastic conduit on 
spacers--6" would be better.  Keep me posted on the results.  I've done 
similar things. k7gco
