PY6CJ 80/40 meters dipole
- A center feed trapped dipole for 80 and 40 meter band in spanish
NVI 40 Meter Antenna Modeling
- The idea of using a low mount dipole, enhanced with reflector wires directly beneath the dipole, on the ground, appears to be a very good approach to creating an NVI specific antenna for local HF operation.
Portable dipole for 40 Meters band
- Pictures and swr reports for a portable dipole antenna for 40 meters band in german
JA7KPI Windom antenna for 40-80
- The total length of this antenna is 41m, height is about 11m, and diameter of element is 2mm.
JA7KPI modified this antenna originally used as Inverted-V type of 80m band Dipole.
Works on 40 - 80 meters band with acceptable swr.
K0FF's 6 meter SLOOP antenna
- It is more or less omni-directional, and horizontally polarized, it's just a dipole folded around on itself, and supported at the far (open) end with a plastic insulator.
Coax Dipole Calculator
- An efficient program to calculate dimensions of coax dipoles, or bazooka antennas considering velocity length of different coax cables. Express dimensions in feet/inch and meters/cm. Freeware by VE3SQB
Folding the Dipole
- Invented by Heinrich Hertz in around 1886, the half wave dipole is still one of the most simple and practical of antennas and still very much in use today. It consists of a half wavelength long centre fed conductor
QRP Fan Dipole

6-Band Windom antenna
pop
- Theory and construction of a novel trapless center-loaded off-center-fed (cl-ocf) dipole or windom antenna for the 80, 40, 30, 20, 15 and 10m hf amateur radio (ham) bands
OCF Dipole - 7 band
- 7 Band OCF Antenna project by W0HC
Bicone antenna
- This antenna is a simple double bowtie biconical dipole design. It was designed as a broadband scanner antenna resonant on the 2 meter ham band.
DCTL Antennas and other compact antennas
- The Distributed Capacitance Twisted Loop is an inexpensive, effective, resonant alternative that can fit in a 8' tall by 12' or so wide space, like a wall, or balcony, even on 80 meters. 160 meters from an apartment, a full wave look and a cage dipole
Emtech ZM-2 Antenna Tuner Kit
- The Emtech ZM-2 Antenna Tuner is a nifty little portable transmatch for QRP (low power). It utilizes the well-known Z-match circuit, which is especially useful for balanced antennas (like dipoles and loops).
D3 Antenna for Field Day
- D3+ High Performance Antennas for Field Day.
This article describes versatile broadband wire antennas. These antennas will double your effective radiated power over a dipole, will be easy and inexpensive to build and install, and will be simple to match.
