30 meter full quarter wave vertical
A view of the antenna and stand from a few feet away. You can't see the radials but they are there. There are four of them spaced 90 degrees apart and about a 10 to 15 degree slope. The antenna has about a 1.2-1 SWR on 30 meters. Notice the trees in the background. Does it look like the wind is blowing? It is as is usually the case out here

30 Meter beam, N6JV
The 30 meter band is very narrow and therefore a shortened antenna isn't a great disadvantage

The antenna described in this article is a ground plane type quarter wave vertical designed to be used on the 30 meter 10.100 – 10.150 Mhz amateur radio band
30 Meter Wire Antennas calculations
The measurements below are for building a simple Dipole Antenna. The Wire Size can range from 16 AWG to 12 AWG. The larger the wire, the wider the bandwidth
30 Meter Vertical Dipole, W1TR
The 30 Meter Vertical Dipole is constructed from #10 stranded insulated wire available in most hardware stores

Take off angle of horizontal antenna For horizontal polarization, the electric field will move sideways on a horizontal plane, while for vertical polarization it will oscillate up and down on a vertical plane
