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


Linear-loaded-short-dipole-21mhz

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band
