Andrew LDF4-50, 26 Feet of 1/2 inch Heliax Hard Line Used in Excellent Condition with 2 Male N Connector *PICKUP ONLY*

 This length of 1/2 inch line is getting very hard to find!

NOTE: This is a PICKUP ITEM ONLY. I live near Green Bay Wisconsin just minutes from Highway 41 North.

This roll of hardline was made available to me and has been stored indoors. 

 It is in excellent condition and half price of new.
