With a pair of KAT100s and a pair of K2s, I need to send 12v up the openline 
feeder to control a latching relay at the top of the tower. The easiest way 
would be to run the dc on the feedline.and it would be even easier.. if the 
isolator would stop the dc from continuing on through the antenna.. that is 
also a dc short, inone of its configurations. I can insert the dc in the 
shack.. with a coax "T"... but there isn't a coax place at the top of the 
tower.Thoughts or ideas?

Have a great day,
