A Lowband Antenna that is Almost Free  ^pop - The Shunt-fed Tower, an effective Low Band Antenna, uses your beam as a capacitive top-hat and only needs a simple feed network and a good ground system to work DX on 80M and 160M.

A multi-band super mini loop antenna - To build this antenna you need a lot that is at least 100 feet across. Antenna covers all bands 80-10 meters + 30, 17, 12 meter WARC Bands

PA0NHC 80/40mtrs dipole antenna - Dipole antenna for 80 to 20 mtrs with END-coax feed by PA0NHC

Switchable Antenna 80/160 meters band Priority listing - A switchable antenna for 80/160 meters by IK1ZOY. A new version of a 1/4L 80 m. dipole modified for use in 160 m. band. using it's own coaxial cable feeder to wrap a coil.

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

80 Meter Multiband doublet antenna - 80 meter multiband doublet antenna with open wire feedline for 80-10 meters by N1LO

802.11b Antenna on the Cheap - Build a 802.11b antenna using PVC, some cheap copper tubing, a Pringles can, and some scrap cardboard, in a few hours. Tests state a 12db gain on 2.4 Ghz

New HF antenna HB9ABX  ^{updated  pop} - A new, revolutionary design allows the construction of small HF antennas, which provide the same efficiency as large antennas. This antenna can be built for all HF bands, from 10 to 80 m.

Half square antenna - The elevated half square antenna is a very simple antenna that can be constructed from common materials yet gives significant improvement over a dipole at the same elevation. Ground mounted versions of this antenna are commonly used in amateur radio for 75/80 and 160 meter bands

IC-PCR 1000 in Germany on-line receiver - Icom PCR 1000 HF/VHF/UHF Antenna VHF/UHF Diamond X 50N HF W3D22 80m/40m 34m (111,54 feet) long based in Germany Hamburg JO43XO.

Fax480 - FAX480 was developed to provide for relatively high resolution image transmission on HF, VHF, and UHF amateur radio bands. FAX480 was designed to bridge the gap between conventional slow scan television (SSTV) and conventional facsimile techniques.

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.
