NA4RR Hexbeam salesWe assembled a 1:1 current balun from parts purchased from
A video on barang assembly is also available
This is a 1:1 baran kit $29 (about $4,350)
English instructions are included.

The balun is mounted just below the feed point.
You will need 6 ferrite beads, 1 tying band, and 1 large heat shrink tube.
Attach the cable ties to the coaxial cable at the position where you want to stop the bottom bead.
Remove the 12 half beads from the plastic holder.
Place two half beads around the feeder wire and secure with tape. Attach the remaining beads in the same manner.
Cover the six beads with a larger heat-shrinkable tube.
Make sure there is about 1 inch of tubing room on each side of the bead.
Shrink larger tubes using a heat source such as a heat gun, match, or lighter.
Place the two smaller heat-shrinkable tubes over the shrunken portion of the larger heat-shrinkable tube,
Firmly contract and secure.
For a video of the installation process,Retrieved from " https:https://youtu.be/ysAFhh1SO6Mfor more information.
Remove the snap core core from the holder.
The holder will not fit into the heat shrink tube if it is still attached.
Don't forget to thread one of the two heat shrink tubes that are cut smaller first!
Slip on the ties and temporarily fix the core with vinyl tape.
Heat shrink tubing is then placed over the core.
I had a little trouble with the insert because the size was just too small.
Heat gun I bought for heat shrink tubing for coils with the intention of making a multi-band dipole before.
Dipoles are full size without trap coils.
I didn't use it because I used a Fan-out Dipole Antenna (Fan-out Dipole Antenna) 
25/03/05 28MHz antenna modification
Shrink the whole thing with a heat gun.
For waterproofing? Double up with small heat-shrink tubing.

It will be a while before I can buy a pipe for the antenna.
