- An Attic Coaxial-Cable trap dipole for 10, 15, 20, 30, 40, and 80 meters
- Antennas for HF mobile operation
- The following description should give you guidance on how to build a mobile antenna for HF bands yourself, using a very cheap CB-mobile whip antenna base. Antennas for mobile operation 7Mhz ,10Mhz, 14Mhz, 18Mhz, 21Mhz, 24Mhz,28-430Mhz
- 40 thru 10 Meter Zepp Antenna
- A modified 20 meter double zepp wire Operating Bands: 40 thru 10 meters (with tuner), basic construction and performance information.
- W5GI Mystery Antenna
- A multi-band wire antenna that performs exceptionally well even though it confounds antenna modeling software.
This antenna covers 80 to 6 meters with low feed point impedance and will work with most radios, with or without an antenna tuner. It is approximately 100 feet long, can handle the legal limit, and is easy and inexpensive to build. It’s similar to a G5RV but a much better performer especially on 20 meters.
- A magnetic loop antenna for HF
- Able to cover all frequencies between 3.5 and about 10 MHz, the loop described here is directional, does not require a radial system, and stands just 1.8 metres tall. Most parts needed can be purchased at a hardware shop. The antenna can be put together in an afternoon and requires only hand tools to assemble. It should cost less than sixty dollars to build.
