- W5GI Mystery Antenna
- W5GI Mystery Antenna is 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 is similar to a G5RV but a much better performer especially on 20 meters.

- Circular Loop Antenna Calculator
- This free online circular loop antenna calculator uses a wire grid method of moments formulation to model a single circular loop with a single feed point. The electric current is computed and used to construct the far zone radiation power pattern. The input impedance and directivity are also computed.

- 20 thru 10 Meter Fan Dipole
- The 20 thru 10 meter dipole is constructed from #10 stranded insulated wire available in most hardware stores.
The feedpoint uses an 8 inch long section of 2 inch diameter PVC pipe. A section of wire joins the elements at either side of the feedpoint to avoid the inductance of square knots that I use on lower frequencies by W1TR

- Cheap antenna to make from 160m - 6m
- The antenna is nothing more than a simple 2.4 metre square loop drawing pinned to the internal brick wall of the spare bedroom. Yep, thats right, the inside wall of the spare bedroom - ideal for flat dwellers, hotel rooms or whinging neighbours, The loop has a simple switched inductance at the top of the square loop and uses a simple coaxial stub to tune the antenna. An additional variable capacitor placed across the feedpoint can be used to fine tune the resonance of the antenna, by Andy G0FTD

- DK7ZB 144 mhz Yagis
- High gain, good pattern and acceptable bandwidth. These aims can be realized with a radiation-resistance of 25-35Ohms, because the 28-Ohm-feedpoint is very simple to match.

- Radio Distance Software
- This is a trivial program which calculates the distance and the bearing between two points. Points are either entered as geogr. data (Latitude/Longitude) or as qth-locator in the Maidenhead format (6 or 8 digits), as used in ham radio. Output is in degrees [°] for bearings, in Kilometer [km], US statute miles [mi] or nautical miles [nm] for distance
