Building and Exploring EH antennas. This is where you have instructions on building a 6 foot 80M antenna and several 20M antennas under 2 feet. Other amateur radio activities are also presented.
Home QTH is Conroe, Texas - USA
80 Meter - 6 foot EH antenna
I hold an Amateur Radio Advanced Class License. I have been an amateur radio operator (ham) since 1965. I was first licensed as WB4AOY in Alabama. When I moved to California I was licensed as WB6ZES. In 1970, I moved to Conroe, Texas (about 30 mile north of Houston) and got my current call WB5CXC. I work in Hong Kong on a 28 day rotation and hold a full class amateur radio operator license in Hong Kong - VR2LB.
I'm active on 2 meters and HF. I'm an active member of the Montgomery County ARES and check into the State Wide ARES net on 80 Meters as well as the local ARES net on 2 meters. I also check into several traffic nets and the Gulf Coast Hurricane net.
EH Antennas: On the web site are details on how to build a 80 M - 6 foot antenna, a 20 M 1 foot antenna, and larger bandwidth 20M EH antenna. These EH are limited space antennas and work well. I built the 80 M antenna first to see if it could give a better signal to check into the 80 M nets. I was using an 80 M dipole made from mobile whips up about 18 feet, and a vertical antenna mounted on the ground without any radials. The EH antenna is about 12 feet in the air and it outperforms both of my other antennas. The first night I checked into the ARES net without any relays. I then checked into the Southwest Traffic net with the net control in Hot Springs Ark. with a 5 9 signal. Not bad for a 6 foot 80 M antenna.
For those of you who are skeptics - click on the link and read some results: http://www.omnirep.ch/eh-test_qrp_en
EH Antenna Design and Construction: These pages will take you through the design and construction of a EH Antenna. Using the these tools you will be able to design and build different models of the 'STAR' EH antenna.
10M Vertical Dipole Construction: This page illustrates the building of a 10 M Vertical Dipole using copper pipe and PVC pipe. These antenna have a very low angle of radiation and are easy to build. Also there are details for building a 6M antenna using the same techniques.
Operations: Need information about Amateur Radio? Visit the Operations page for information about becoming a Amateur Radio Operator (ham) or for helpful information.
Echolink: Use your personal computer and the Internet to link up to repeaters and talk to amateurs in far away places. This is a great mode for Technician class hams who want to talk to hams in other countries etc. It is also a good way to keep in contact with the guys back home when you are on vacation etc.
PSK-31: Using the sound card on your computer you can start to enjoy this new mode of operation. On the site you can get an introduction into the basics of equipment, programs, and interfaces. Due to the characteristics of this mode it is possible for the station with low power and normal antennas to work some really good DX.
Hi-Tech Antenna Test Range: This is my antenna testing range. As you can see it is Hi-Tech. HiHi
Solar Data Retrieval Program: This is an Excel spreadsheet program that will retrieve solar data from the government web site and put it on a form. I started this as I was always trying to find the solar data to enter into propagation programs.
PIC Projects: PICs are IC that are microcontrollers. You might have heard of BASIC Stamps which are based on PICs. I have experimented with several PICs and have done several projects using them. On this page I will describe basic information on what is needed, etc.
QRP & Building Kits: When I first got interested in amateur radio, everyone I knew built their own equipment either from scratch or from a kit. QRP has opened up an new era for kit building. I have built the Rock Mite 20, a 20 meter transceiver that is 2" X 2 1/2". If you have never built your own radio, now might be the time. They are very inexpensive and a lot of FUN!!!
Thank You for visiting my web site. I try and update it every month or when I get new data. I add new pages periodically and update the content on the old pages. If you have any suggestion dealing with the web site or content please E-mail. Drop in again. See you on the air.
