Here are MANY J-Pole Antennas to Build.
- 50MHz J-Pole
Antenna pop- Need a
general purpose antenna on the magic band? The J-Pole is an easy-to-build
and inexpensive device that provides an omni-directional vertically
polarised antenna without the need for a ground plane. In technical terms,
it is an end fed vertical 1/2 wave which is fed via a 1/4 wave matching
stub.
Easy J-pole
antenna pop- Everybody
says keep one in your bag, nobody seems to make one work right. Here's the
straight scoop on why the J-pole is not an easy antenna to duplicate!
- J Pole
calculator pop - Enter the
operating frequency and calculate dimensions of your jpole antenna
- J-Pole theory
pop- The J-Pole antenna is an
omnidirectional antenna that can be used for base, mobile and field day
stations. It does not need a ground plane, radials or a complicated
matching system. The J-Pole can be cheaply, simply and quickly constructed
using a variety of techniques, some of which are discussed in this
article.

Antennas pop - 4 Element
Cubical Quad, Yagis, LZA Circular Quad, Shrunken Quad , quarter wave,
J-Pole, beam mounting , changing polarity
- 300 Ohm
Twin-Lead J-Pole - popular 2-meter emergency antenna
that can be found all over the internet and in antenna books.
- 440 Mhz J-Pole
Antenna plans- Here is a 70cm (440 Mhz) J-Pole
antenna that is inexpensive, and easy to build. Author use 1/2 inch copper
pipe, and the associated fittings necessary. The dimensions aren’t
typical however, this is what it took to get its SWR low.
- 50 Mhz J-pole
antenna- A project for a jpole antenna for the six
meters band. Includes dimensions building instructions and pictures of the
assemblig phases. In Italian
- Concealed DSS
J-Pole - The idea here is to have my antenna high in
the air, in free space, with the dish mounted close by for concealment.

Antennas- Conejo
Valley Amateur Radio Club,
article edited by Rory Eikland, KG6HCU and Ken Larson, KJ6RZ, they have
had excellent experience building and using J-Pole antennas, and share
their experience on planning VHF and UHF Jpole antennas.

Own Super J Pole - Javascript for calculating the
lengths of tubing to be used for the construction of a Super J-Pole in a
collinear design
- Dual Band J
Pole- Dual band J pole operational over the entire
6Mtr band (50 – 54MHz) and the entire 2Mtr band (144 – 148MHz),
slightly favouring the upper half of both bands by VK6YSF
- Folding J-Pole
Antenna- Also known as the Backpacker's Delight
Antenna. This Folding J Pole Antenna is the original design of Mike Heiler
KAØZLG and was featured on the Front Cover of the March 2005 QST Magazine.
- GMRS J-Pole
Antenna- Build a j-pole antenna for the GMRS/FRS
radios. These radios are the type you can buy at sporting goods stores
such as REI, Cabelas, etc. There are several radio manufactureres who make
GMRS/FRS radios with removable antennas. This antenna can increase the
range of these radios by miles!

Meters QST February 1950, Easy to build J-Pole antenna for restricted
space.
- J-Pole Antennas
for 2 Meters- This paper describes two types of 2
meter J-Pole antennas, one made of copper pipe and a roll-up J-pole made
of TV twin lead. The figures give the details of the dimensions,
components and construction.

- KG0ZP Copper
Cactus Antenna- The antenna may be built as a
Mono-Bander, Duo-Bander, Tri-Bander, Quad-Bander or whatever with great
success. Dimensions for 52 146 223 435 912 and 1265 Mhz
- Mirrored
J-Pole updated - The
mirror-image J-Pole is very easy to construct and requires only two
T-Fittings plus a length of copper pipe.
- Plumbers
Delight J Pole Antenna Project- This article was reprinted
to assist new hams at building their own 2 metre antenna. This design is
very rugged and can be built for a few dollars with most of the parts
available at your local Home Depot.
- Super J-Pole
for 435MHz updated- The Super
J Pole antenna is a co-linear vertical consisting of a number of half wave
length vertical elements separated with half-wave length stubs (Tuning
stub) feed with a folded matching stub by vk6ysf
- Super J-Pole
plans- The super J-pole is a regular J-pole antenna
with a 1/2 wave element mounted above with a 1/2 wave phasing harness
connecting the element to the bottom part of the J-pole. The antenna can
be built for any band, but I built mine for 2 meters
- The DBJ-1
VHF-UHF Dual Band J-Pole- Searching for an
inexpensive, high performance dual band base antenna for VHF and UHF ?
Build a simple antenna that uses a single feed line for less than $10.
- The DBJ-2
portable J-Pole- A Portable VHF-UHF Roll-up J-pole
