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

30 Meter and 17 and 6 meter ground plane antenna. DIY, K7EA
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


Linear-loaded-short-dipole-21mhz

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band

Atu balanced feeder antenna system

Atu balanced feeder antenna system An ATU has the advantage of bringing the feeder-antenna system to resonance, act as a band pass filter both on receive and transmit and a low SWR
