Swiss Quad for 10 and 6 meters  ^pop - Based on HB9CV, F6ITV decribes how build a swiss quand antenna for 28 and 50 Mhz.

M3FVB 2 meter quad - Photos and building procedure for a home brew 2 elements Quad for 144 mhz.

80M Vertical antenna with capacitance hat  ^pop - Simple wire antenna cheap to make, using readily available materials, Low angle radiation, with rejection of high angle signals Wide bandwidth, with resonance at the 80M DX window (3.790-3.800 MHz); and Maximum height is 40 feet

The Double Bazooka Antenna - The Double Bazooka Dipole is a very efficient single band antenna which is very quite, and does not require the use of a balun. This antenna consists of coax (RG58) or other 50 ohm type with the shield split at the center and the feedline attached to the open ends

How to make an end-fed antenna work  ^pop - Here is a sure fire way to make end-fed halfwave antennas fed with a 50 ohm coupler work - without long radials, grounds, chokes, voodoo.

50-MHz Real Audio Clips - Audio clips from cycle 20 to cycle 23, includes some interesting audio files dated 1969 and 1979.

The PA2S 50 MHz Tape Archives - The PA2S Tape Archives. Many RealAudio sound clips of 50 MHz DX contacts, recorded during solar cycle 21 and 22.

KVK Antenna Systems - The manufacturer of the NuBeam, Vipole, and the multi-band Quad-Folded-Dipole (or QFD for short) antenna. Also have a unique multiband vertical which can combine operation on multiple HF frequencies as well as provide high gain on 50, 144 and 438MHz in a single antenna.

Really Low Frequency Operating - The world below 500 kHz (The wavelength is 1500 meters or just about a mile) has a number of interesting listening and communications opportunities with possibly more to come.

WA4DSY 56KB RF Modem - This is a prototype of the WA4DSY 56KB RF modem. It is intended for use on amateur packet radio networks. The modem generates RF in the 28 to 30 mhz range and requires and linear transverter to convert the signal to a UHF or microwave ham band

A low power 3.5MHz ARDF transmitter - This low power transmitter is developed for ARDF exercising purposes but of course can be used as super QRP transmitter either. With 1 or 2 meter wire as antenna and a ARDF receiver with ferrite-rod antenna the range is about 100m but with better antennas and a 'real' receiver the range is probably much larger.
