Vertical antenna for 160 meter - This high antenna require a large ground composed by 40 radials. It's not very handy expecially in windy situations but is very powerfull in pile-ups. In italian

2 Meter 10 Element Quagi Antenna - This antenna was designed by N6JSX Kuby for Transmitter hiding. Fitting the requirements of directionality, high gain, and portability. This antenna was derived from the ARRL Handbook information on Quagi's and Yagi's; in the absence of two meter Quagi information, UHF Quagi dimensions were scaled into 146 MHz use.

Slim Jim 2m Vertical - This VHF 145 MHz antenna is easy to build and with no radials. It shows equal gain of 5/8 lambda. It is light weight, you can hang it somewhere (on a tree may be) and work.

The flower pot antenna - A portable dual-band antenna working principally on 10 meters but also close to the 30 meter band. It�s compact, light, economical and doesn�t need any radial.

Top Loaded Portable Vertical - A 3.5 Mhz top loaded vertical antenna built using 2 elevated radials by DJ9RB

Radial System Design - Are the lengths of antenna radials related to the height of a vertical? By N6LF

An End Fed Half Wave Antenna - This end fed type of antenna was marketted in the UK and is a useful system for the portable set-up. Being a half wave, no radials or counterpose wires are needed.

Short radials for ground-plane antennas - Think your elevated radials always have to be full size? N6LF lets you in on some great ideas to lessen the “wingspan” of radials, especially near the beach.

Dish 802.11 Wireless Networking Antenna - This antenna modification is for the IEEE 802.11b networking protocol that operates at 2.4 GHz. It can be scaled easily to the 5 GHz frequency used by IEEE 802.11a by simply scaling the dimensions on the feed can and the excitation antenna to 2.4/5 = 48% of the dimensions shown above.

NOAA Space Weather Scales - The NOAA Space Weather Scales were introduced as a way to communicate to the general public the current and future space weather conditions and their possible effects on people and systems. The scales describe the environmental disturbances for three event types: geomagnetic storms, solar radiation storms, and radio blackouts.

Troubleshooting Traps - This article refers mainly to the old Cushcraft 1/4 wavelength AV series of antennas (12AVQ, 14AVQ etc) hence the references to radials. The R series (R5, R7 etc) are 1/2 wavelength antennas, and the radials are NOT 1/4 wavelength resonant.

Javascript antenna calculations - Javascript online calculators for dipole 5/8 verticals with radials, and delta loop antennas

Meter - This meter scale drawing program is designed to have a computer do the hard work in making a precision scale for a d'Arsonval analog meter. The resulting scales will typically be nicer-looking than those found on many commercial meters.

EasyPal - Easypal is a freeware DSSTV software uses the DRM (Digital Radio Mondiale) encoding to allow the sending of image files over voice channels. This mode is known as Digital SSTV

DTMF decoder - A very easy to use program to decode DTMF dial tones found on telephone lines with touch tone phones. The DTMF Decoder is also used for receiving data transmissions over the air in amateur radio frequency bands.

DTMF encoder - Generates dial tones using the Soundcard. A neat tool for sending out short sequences of DTMF tones.
