Shorty Forty Antenna
- Short dipole antenna for 40 meter ham band.
Can be put up in the space required for a 20 meter dipole.
40 meter shortened dipole - M0MCX
- Interesting little project with a couple of loading coils by M0MCX
40-80 Half-Extended Double Zepp Antenna
- A dual-bander for 80M and 40m. An Extended Double Zepp (EDZ) is a 5/4 wavelength center-fed dipole.
This article will introduce the Half-Extended Double Zepp (HEDZ) which has characteristics that a lot of amateur radio operators should find quite interesting
Bazooka dipole for 70 cm band
- Here is a very simple 70cms dipole from Harald PD2HFE, which uses a single piece of
RG-213 coaxial cable 34 cms in length.
Bazooka antennas compared to dipoles
- Article and comparison between bazooka antennas and dipole, taking care of effieciency and bandwidth
The Broadband Double-Bazooka

The Monoband HF dipole antenna
- If you are looking for an easy antenna for your favorite band, you can't go wrong with an halfwavelenght dipole, all you need is 3 insulators and some wire
Dipole Height
pop
- How High should my Dipole be?
Dipole Antennas and the effect of height above ground

A 5 band log periodic dipole array
- Modified version of the Telerana antenna which was orginially featured in the July 1979 issue of QST. The array is suspended within a framework made of fiberglass poles emanating from a central hub with the ends tied together with light weight rope around the perimeter. 10-15-20-30-40 meter band coverage
The full-wave loop antenna
- These omnidirectional antennas offer Horizontal polarization, and about 2.1 dbd of gain. They are much quieter than a dipole or a vertical, have a broader bandwidth and will usually out perform a dipole antenna.
The Fan-tenna
- A Safety multi-band mobile antenna by Robert Wilson, AL7KK
An automatically tuned 7-30MHz mobile antenna
- This is a base-loaded vertical antenna that mounts on the car's roof. The loading coil is designed as a variable inductor, with a three-legged chariot that travels up and down inside the coil, with grooved brass wheels running on the coil turns, and driven by a slotted rotor tube.

Mini-Beam Geometry Basics
- There is a natural progression of the geometry of
the "mini-beams" deriving from the basic yagi, which in itself owes a lot to the common dipole. By Dick Stevens, N1RCT
CSVHFS Antenna Gain Measurements
- The Central States VHF Society has conducted Antenna Gain Measurements since its inception in 1967. Comparisons between commercial and homebrew antennas, between different homebrew designs, and between different commercial designs. Mostly VHF UHF and up antennas.
