Antennas : 40M : 40 meter Magnetic Loop Antennas
- 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. The antenna can be put together in a short time and is cheap by Peter Parker VK3YE ex VK1PK

- 50MHz J-Pole Antenna
- Need a general purpose antenna on the magic band? The J-Pole is an easy-to-build and inexpensive device that provides an omni-directional vertically polarised antenna without the need for a ground plane. In technical terms, it is an end fed vertical 1/2 wave which is fed via a 1/4 wave matching stub.

- The Simple Collinear
- Wherever there is a need for a vertically polarized omni-directional antenna with gain, a collinear is used. The vertically polarized collinear takes the form of two or more half waves in-line and in-phase, resulting in an omni-directional pattern with maximum radiation near the horizon.

- The full-wave loop antenna
- These omnidirectional antennas offer Horizontal polarization, and about 2.1 dbd of gain. They are much quieter than a dipole or a vertical, have a broader bandwidth and will usually out perform a dipole antenna.

- Remotely-tuned loop antenna for LW and MW
- This article describes how to build a loop antenna for low frequency (LF) and medium wave (MW) reception with remote-controlled tuning. The antenna is extremely sensitive and can be built mostly from parts from old radios and tape recorders. Like all loop antennas, it is highly directional, which allows you to null out unwanted noise sources.

- Build your first dipole
- The dipole antenna is an easily designed and made antenna usually used on HF, although can be (and sometimes is) made for VHF and UHF antennas, and in varying forms is also used as part of different designs of antennas – i.e. as the driven element for directional antennas.

- Meter Mate - SWR Graph Software
- Meter Mate is a companion utility for your directional watt meter that allows you to calculate the SWR reading when the forward and reflected power readings are measured. In addition to calculating the antenna system SWR Meter Mate will also plot the SWR curves of all of your antennas onto graphs that may be printed out.
