40 dipole

2 meter dipole antenna - Pictures comments and detail on a 2 elements antenna for 2 meters band

Build a hanging dipole for two metres - Described here is a simple omnidirectional, vertically-polarised dipole for two metres

W1ZY 40 meter moxon antenna - W1ZY's 40 Meter MOXON is the product of 9 months of experimentation. The final array is reversible and constructed from No. 12 insulated wire fed through two RF current baluns

40-meter Rectangular Loop Antenna - A 40-meter antenna that provides good local and regional coverage during the day and good DX capability at night

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.

Six Metre Portable Dipole - A portable dipole for six meters band

QRP 80 Metre Slinky Dipole - M0WYM slinky dipole setup into an attic.

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 - Attic dipole antenna that allow to operate QRP from 40 metres to 10 metres, specifically 40, 20, 17, 15 & 10 metres by M0WYM

HF Magnetic Loop Antenna - Local and DX contacts from tight spaces, it works from 40 to 17 meters

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).

Backyard 7 Mhz Vertical - A vertical antenna for 40 meters band by PA5MW

Windom for 80-40-20-10 m - A windom multiband antenna for 80 40 20 and 10 meters band. Include picture for a 1:6 Balun. In french

IZ3DVW/B - 40meter band beacon on 7,039.6 MHz

VE5-URC Amateur Radio Club - Unity is situated about 2 hours North West of Saskatoon.

TAK-tenna Priority listing - Electrical half-wave dipoles HF antennas

A low cost 600 watt ultra-linear amplifier  ^pop - This compact little amplifier is the brain-child of Pat Murdoch, ZL1AXB, in Auckland, New Zealand. It is only 11" wide, 4" high, and 9" deep. Operates for 40, 20, 17, 15, 12, and 10m

500mw CW Transmitter - A very quick and easy way to get on the air is to build a "Michigan Mighty Mite" CW transmitter for 160, 80, 40 or 30 meters. It can't get simpler than this. It has very few parts, costs almost nothing, and it works! Cost estimate $10 by VE6WTF

PSK31 Interface - Fairly simple way to interface a computer soundcard to an HF rig to operate PSK31. This interface also works for SSTV & RTTY, and has been tested with a Kenwood TS-140.
