30 meter antenna Links →
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
