W5GI Mystery Antenna ^pop - 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.

Beverage Antenna Construction - Types of beverage wires, choose best supports and insulators, multiple antennas at one feedpoint, all well documented with photos and exaustive explanation. This article offers insights on building Beverage antennas for optimal reception. Key takeaways include using strong wire (copperweld or electric fence), proper termination, and a good grounding system (multiple copper rods). The author recommends maximizing antenna length and orienting it towards desired stations. For best results, utilize an antenna tuner and experiment with termination resistors.

20 thru 10 Meter Fan Dipole - The 20 thru 10 meter dipole is constructed from 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 used on lower frequencies.

Improving Gain of the Super J-Pole Antenna - The collinear J-Pole, often known as the Super-J, does improve the behavior over a regular J-Pole. there is an advantage when vertically combining 1/2 radiating sections to have a bit of separation between the half-wave end points. Get 0.8 dB more gain out of the trusty Super-J by replacing the traditional phasing stub with a long coil.

OCF Dipole - This is a popular antenna design as the performance is very good across the HF bands and requires little or no tuning. It is a dipole fed off center with a 4:1 current balun at the offset feedpoint. The antenna shown covers 80, 40, 20 and 10 meters with 15 meters and WARC bands

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
