About vertical antennas by W1ICP
Putting your first ham radio station together can be an expensive proposition. One way to cut costs is to keep the antenna simple. Here’s how WB1FSB shaved the price and provided four band operation. https://drive.google.com/file/d/1os8GDj9Ydcp93W6r9TxBPJXp7zqPJOGu/preview
The basic antenna is a vertical monopole, using elevated radials to complete the “ground plane.” I use it only on the weekends, primarily for contests, thus it is designed to be raised and lowered with a minimum of fuss. It is a full-size 40 meter 1/4 wavelength vertical, with from four to eight tuned radials
Design Criteria: Simple wire antenna; Cheap to make, using readily available materials; Low angle radiation, with rejection of high angle signals; Wide bandwidth, with resonance at the 80M DX window (3.790-3.800 MHz); and Maximum height is 40 feet (limitation due to treeheight). Design: Since the use of a full ¼-wave vertical was out of the
One of the most useful antennas in the repertoire is the Marconi or quarter wave grounded vertical antenna. Its invention made it possible to halve the length of antennas, simplifying communications, especially at HF and below.
Quickie Vertical Hear I am sitting in front of the rig listening to everyone working CQ World Wide, and I don’t really have time for this, but I hear a few interesting stations on 20 meters and try to call them. Trying to bust the pile up with 100 watts and my hustler dipole is
Omnidirectional Antennas “Omnidirectional” is generic term for an antenna that radiates equally well in all directions. There are several antennas that are considered omnidirectional. 1/2 Wavelength Vertical Most folks lump all vertical omnidirectional antennas into the same category and call them “Ground Planes”. A ground plane antenna is actually an antenna similar to the vertical
PY1BEK Vertical antenna for ham radio – 40-meter ham band (7 MHz) This self-supported vertical antenna was made with aluminum tubes of 3 m in length that have an external diameter of 32 mm and a wall thickness of 1.2 mm. The total length of the radiating system is 10.33 m and its square-shaped base
I’m evaluating these HF Multiband vertical Antennas. – GAP Titan DX – Cushcraft R8 – Ecomet 7+ – Butternut HF6V – Hy-Gain AV-640 At time writing the preference is going to the GAP antenna… I will post soon here some more reports from reviews and tech specifications as well as best prices from european dealers.
