Because of Corona, life is somewhat limited. Good thing the hardware stores are still open.
For my /P activities on 2m I have a 6 Elt.Yagi with 2m boom to DK7ZB. I have divided the boom in the middle. I found it very practical to have everything in one quiver. However, it turned out that a quiver with more than one meter length is not practical for hiking. Besides, it brings my telescopic mast to the limit.
The 4x Oblong I prefer has a small packing size and is light. It is really good - but only in calm weather.
The other day I was on the summit and wanted to be active with the transverter also on 2m. It was really windy and the Oblong made the biggest problems because of its surface.
I wanted to have a new antenna. I wanted the following features:
Small and easy to transport, not wind sensitive, wide bandwidth, no tools needed, 50 Ohm
(As I have always been a fan of antenna arrays, I wanted to be able to expand them to achieve more gain.)
The collection of DK7ZB let me find it:
A 50 Ohm 3 Elt. yagi with almost 5dBd, boom 50cm and thus half of the element length. Large bandwidth and therefore uncritical in construction. Can be operated individually or as a group.
The ideas for the details came during a walk through the hardware store. You can see them in the pictures. Now I only have to sew a quiver.
Elements are 6mm aluminium, screws with 4mm were pressed in with a vice, 4mm threaded sleeves were drilled through and fixed with 3mm screws in the boom. The length of the threaded sleeve was naturally taken into account in the length of the elements.
