© WB5CXC 2011
Welcome to my web site. I have been licensed since 1964 and hold an Advanced class license. I
was first licensed as WB4AOY, and then I moved to California and became WB6ZES, I moved to
Texas in 1960 and became WB5CXC. When I worked in Hong Kong I had the call VR2LB.
I enjoy making antennas and see how they work. I have built quite a few over the years, some work
good and some are almost dummy loads. I like to build them using common available parts from
hardware store etc. you will see my favorite construction materials - wire & PVC pipe.
Operating: This tab has our APE (August PSK Expedition) which is an event from the PODXS
070 club. 2013 was my second year to go this event. It is a lot of fun and you get to talk to some
Projects: The Woodland ARC built some Antenna Wire Launchers (Spud Gun). We have built the
some other projects that I will add later. These are projects that can be done as a club project.
Presentations: These are presentations that I have presented at Ham Com in Plano, Tx and
other presentation that I have presented at radio clubs etc. Most of the presentation are for entry
level amateur radio operators with math etc. kept to low level. Most of the presentations were the
result of someone asking questions on different subjects and I made a presentation for other that
might be asking the same questions. Most all the presentation are in Power Point.
I picked some of the one that I though would be useful to others. You can down load them and use
them at your radio club meeting. Some of them you will probably need to modify for your location,
and other specific item for your club.
HF Antennas: This section has HF antennas that I have built or are going to build. I have built all
of them except the Vertical T Bar.
The End Fed antenna was a presentation at Ham Com 2013 and was a result of trying to get a
better every day antenna and also a portable / emergency antenna. I use this with a 33’ fiberglass
pole as a support, it makes a very good HOA antenna, you can put it up and take it down in about 5
Most of these antennas are easy to build even if you have never built an antenna before. It is really
a neat feeling when you build an antenna and it really works.
VHF / UHF Antennas: In this section are construction details etc. on building VHF / UHF
antennas. I have built several of these antennas. Our ARES group have built 2M Moxon antennas
several times as a group project.
Some of these antenna designs are from a German amateur radio operator DK7ZB. He is well know
in Europe for his VHF / UHF antenna designs. His designs regularly wins the antenna competitions.
I have picked some of the designs that I thought would be good to make. You can see several of the
antennas I have built from his designs. I take his dimension and use my favorite materials to built
them (PVC and wire etc.). He has some unique designs using an ‘Open Sleeve’ which is a static
elements but acts as a driven element. It is very close to the driven element.
EH Antenna: EH antennas are small antennas that have a unique design. I have built several of
these and used them.
I haven’t built any for several years but still keep the data for anyone that wants to build one.

J-Poles: This section has J-Poles antennas. You can calculate how to build a VHF or UHF
copper Cactus antenna. There is a web page on adding adjustment screws to copper cactus
antenna to tune it. There are measurements on building Twin-Lead portable J-Pole for your go-
There is a page on building HF J-Poles using 450 ohm balanced feed line. I have built the 10M,
15, and 20M. I have used the 15M and 10M but didn’t have a way to put up the 20M (it is ~45’
