Welcome to my web site. I have been licensed since 1964 and hold an Advanced class license. I was first licensed as WB4AOY in Alabama, and then I moved to California and became WB6ZES, and when I moved to Texas in 1970 I became WB5CXC. I worked in Hong Kong and I had the amateur 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 stores etc. you will see my favorite construction materials are 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 neat people.
Projects:The Woodland ARC built some Antenna Wire Launchers (Spud Gun). We have built 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 that others might be asking the same questions. Most all the presentation are in Power Point. I picked some of the presentations that I thought 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 items 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 minutes. 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!
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-kit. 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’ long).
5 Element Dual Band (2M/70cm) - Single Feed 50 ohm - Light Weight Yagi
From time to time I will feature an Antenna. My first is a Dual Band Single feed 5 element Light Weight Yagi.
PSK Reporter:I added a new page under Operating - called PSK Reporter. The PSK Reporter web site can be used to check the current propagation or to check how your station is getting out.You can transmit a CQ and then go to the PSK Reporter and see who received your CQ. This can be useful if you are trying out a new antenna dor trying to get a particular location.
Web Site updated - March 2015
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.
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 known 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.
New Tab Added - Calculations
Coax Calculator:The Coax Calculator you can determine the loss on your coax cable with and without SWR. Select various Coax types to determine the loss. On the bottom section you can calculate a ¼, ½, or full wavelength stub.
Matching Stub Calculator:You can match two impedances by using a ¼ wavelength of transmission line. The Top section is used to determine the impedance of the required matching stub, Input your transmitter impedance and the antenna impedance and it will calculate the matching stub required. The bottom section will determine the length of coax required for the matching stub. Select the coax to determine the length of coax.
