2 METER 1/2-WAVE J-POLE
Click on these images for more detailed
VHF-FM Antenna Made From 450-Ohm
Great first time J-pole project. Covers
most of the basics.
This small and thin design also makes it good
for several stealth applications.
And......We've nicknamed this design the
This decoupling loop is
sometimes mistaken for a matching balun.
We'll just call it a choke and not put everyone to sleep with a long
discussion of antenna theory. Just a few points on this topic..
Adding a choke like this is a good habit to get into. Another idea
for this is one of those plastic snap-on ferrite cores. They come
in different sizes depending on the size coax used. Either way is
up to you. This J-pole is a balanced antenna going into an unbalanced
feed line and can cause RF to get back into the Rig and into the shack.
Save your equipment and try to protect yourself...
This is easy to do.. So, take this
extra step.. Please be safe..
