This is the half-size version of the G5RV.
You can mount it on a pole in the center using the insulator shown - or any
other insulator of your choice. A short length of PVC tubing will work
fine. You just have to keep the two sides from touching - that's
all. Or, you can suspend it between two objects. Make sure the
300-ohm twinlead is kept away from any metal. It is part of the antenna -- not just a feedline.
It "can" touch wood; but it's best if it doesn't. The copper wire can be any size you want from about #12 to #22.
It should be insulated, such as coil wire or electric motor wire; however, I use Radio Shack ground wire which is stranded and comes
in lengths of 70 ft. It seems to withstand the flexing quite well -- I put it up and down quite often.
The plastic insulator can be plexiglas or something similar. I drilled a couple of holes to mount it on
a wooden mast; then
a couple of more holes to stick a couple of #4 bolts through - one on each side.
Use either crimp-connectors or just twist the wires to connect each side of the 300-ohm to each side of the dipole.
Be sure to weatherproof all connections. Use silicone or coax tape or something like that. The two legs of the dipole "should" come out
close to horizontal; but I have used it with them dropped down to a total angle of about 120 degrees and it
worked fine. Make a tight loop in the end of the wire and run a string to any convenient location, such as a tree
or fence post. Any coax can be used; but 50 ohm matches most transmitters nowadays.
You DO need a tuner. My little Kenwood AT-130 works just fine.
Even the built-in tuners work in most cases. Have fun!
