Default Cushcraft R5/R7 Matching Network (MN-7) Rebuild

...

Anyone have a schematic of the matching network. I have two antennas and
both are missing the box.

Click on ANT, then green dot next to Cushcraft R5, maintenance and repair


Just what I needed, I had bought two antennas at the Shelby hamfest
getting them mostly for tubing and hardware. I may be able to get them on
the air. The fiberglass insulators on mine are shot, Im not sure how I
will repair them. Im thikinking about cutting back the rotten part and
then building it back up with glass cloth and resin.

With the web sites below -- you can build a new R5/R7.
Check A0FRI web page for recommendations on insulator repair.

You could also contact Tom, A9KW at ZeroFive antennas --- IF uses oil filled
nylon
for his vertical insulators
