It is very easy to create a simple 1/2 wave dipole, all you need is some lengths of wire such as the core of some mains flex or even a straightened out metal coat hanger, some co-ax cable and a connector for your scanners antenna input

This antenna can be made in a couple of hours and involves a fair amount of measuring, cutting, bending, and bolting metal.

Using our components you can build a rotating tower with greater capability than 3-4 static towers. A rotating tower allows common rotation of HF stacked arrays, VHF and UHF arrays, and antennas mounted at optimum heights. Component design also allows tower shunt loading and end support for wire antennas

F5NPV explores the construction of a cost-effective 1KW dummy load for radio enthusiasts. Purchasing a commercial dummy load can be expensive, but with basic materials such as a metal can, resistors, mineral oil, and a heat dissipator, you can build your own. The article provides a simple guide to assembling the load, including the importance of testing for inductance. The DIY dummy load yields impressive performance, with an SWR of 1.2:1 across multiple bands and the ability to handle up to 1KW of power. This budget-friendly solution is a valuable addition to any radio shack.

This active antenna for the shortwave band provides surprising performance, even indoors. As the name implies, the main loop is made from a Hula-Hoop with the metallic paint stripped off and a single turn of 14AWG copper wire inserted inside the hoop.

The eggbeater antenna uses on mobile operations using the metal roof of the car as the reflector. The distance between the antenna and the roof as described in this article should be 1/8 lambda.

Initially planned as an article on the R-407 station mast, this project evolved into creating a custom mast kit. Utilizing original materials, the design was modified for cost-effectiveness and practicality in home assembly. The new mast extends to 10 meters, featuring secure connections, a leather-lined base to prevent metal-on-metal friction, and sturdy military-grade anchors. Modifications include lengthened connecting tubes, improved anti-rotation features, and a convenient base design for solo assembly. Ideal for amateur radio operators, this mast provides stability, ease of construction, and versatility, proving more economical than professional products without compromising on performance or reliability.

This project outlines the construction of a simple TEFV (Tilted End-Fed Vertical) antenna suitable for backyard or park installations. The design requires basic materials such as 100 feet of coated stranded copper wire, wood stakes, metal ground rods, a non-conductive fiberglass pole, and essential tools like wire cutters and a soldering iron. The antenna is supported by a 20-33 feet tall pole and includes a 9:1 unun for impedance matching and a resistor for tuning. Step-by-step instructions guide the assembly, from preparing the wire and pole to connecting the unun and resistor, ensuring a functional and durable setup for outdoor use.

Galvanic corrosion, a destructive process triggered by dissimilar metal contact in a corrosive electrolyte, poses a significant threat in antenna manufacturing. With aluminum and stainless steel components commonly involved, unaddressed corrosion can lead to white particle accumulation, causing long-term damage. Awareness of the galvanic series and the application of protective coatings like Alumslip can mitigate this pervasive issue, ensuring a prolonged antenna lifespan.

This article describes a DIY paddle mount for the Icom IC-705 radio. Dissatisfied with the high cost of commercial options, the author builds a mount from sheet metal and scrap materials. Construction utilizes hand tools and readily available supplies. The final design offers adjustable paddle placement and tool-free installation/removal. Initial testing shows promise for improved field operation.

Examines the AOR AR-7030 communications receiver, detailing its technical specifications and operational characteristics. The resource describes its compact design, CNC machined aluminum cabinet, and a frequency range spanning 0-32 MHz. Key features include a ceramic metal cased 4 kHz AM filter, with typical bandwidths of 2.2 kHz, 4.0 kHz, 5.3 kHz, and 9.5 kHz, alongside 400 memory channels and multi-timer functionality. It emphasizes the receiver's high-quality components and a design philosophy focused on reliable performance without superfluous features, making it a dedicated tool for serious listeners. The review assesses the AR-7030's performance within its price class, particularly for **medium wave** and **shortwave** reception. It provides insights into how the receiver's design choices, such as its robust construction and specific filter options, translate into practical listening experiences.
