Ladder Line run from ground support near the tower
over a fence line, about 6 feet off the ground.

We are often asked how do you support the Ladder Line on horizontal
runs above the ground and bring it into the Radio room or Ham Shack.
Below are examples on how K5JYB conquered these two problems.


"T" Post is made of PVC pipe supporting a PVC "T", the material is 1/2" ID.
The vertical portion is supported by the fence. Note that the Ladder Line Spacer is
placed inside the PVC "T" and held in place with electrical black plastic tape.


Here K5JYB has used Radio Shack "Wall-thru Coax Lead-in Tubes" (Radio Shack no longer sells these)

Note there are no splices, wire is one continuous piece
from Ladder Line to Doublet.
