HAM RADIO STORE
International Ham Stores - the sign that means a
GREAT DEAL!
One of the regular calls we get is about HF antennas for small
gardens. I have been working on this and have concluded that
the best option is the End Fed Half Wave. It has a very low
VSWR and requires no external ATU or long coax feeder. The
40m- 10mm version is around 65ft long and can be bent to
fit the garden. We now offer a kit to permit operation on
80m which adds around 9ft to the length. Call our Sales
team who will be happy to help you.
