More Easy Antennas for the VHF/UHF

For the purposes of the next Radio Communications Seminar I constructed 2 antennas.

The first one is a ground plane field antenna using a folding handheld radio antenna.

An SMA to chassis mount adapter is used and the radials are just solid core wire twisted through the adapter mount holes. The good thing about this method is that the antenna requires no tuning as the vertical element is already pretuned.

The second type is the well known DIY ¼ wave groundplane antenna. It uses a SO-329 chassis mount connector as a centre piece, four radials through the mounting holes and a whip of solid core wire.
