End-fed Inverted V for 17-20-30-40 Meters
The 17 meter antenna is mostly a 1/2-wave sloper with an extra 3 feet going down the other side. On 20 it is much the same, just more wire on the side opposite the feedpoint. Only 30 and 40 meters are fully symetrical Vees, but all wires are a full 1/2-wave for the given

A multi-band inverted-V dipole for portable operation
This form of inverted-V allows multi-band operation with one antennafrom portable locations
A Small Garden Antenna
Spacers made from glass fibre sheet cut into strips was used, each 6 inches long. The parallel antenna wires are secured with wire wraps
All band dipole Mk2
The All Band HF Doublet is often referred to as a random length dipole as it is generally as long as the available space within reason, but here are a couple of limitations to the ultimate dipole length
Improvement of a long wire antenna
Spectacular noise reduction thanks to this balun, which is very simple to make using drawer bottoms
Extended Double Zepp Antenna
Install a 4:1 current balun on the end of the 450 ohm latter line stub
